+ BREAKING CHANGES:
+
+ December 17, 2018:
+  - Changed designated initializer on FlutterEngine
+
+ October 5, 2018:
+  - Removed FlutterNavigationController.h/.mm
+  - Changed return signature of `FlutterDartHeadlessCodeRunner.run*` from void
+ to bool
+  - Removed HeadlessPlatformViewIOS
+  - Marked FlutterDartHeadlessCodeRunner deprecated
+
+ August 31, 2018: Marked -[FlutterDartProject
+ initFromDefaultSourceForConfiguration] and FlutterStandardBigInteger as
+ unavailable.
+
+ July 26, 2018: Marked -[FlutterDartProject
+ initFromDefaultSourceForConfiguration] deprecated.
+
+ February 28, 2018: Removed "initWithFLXArchive" and
+ "initWithFLXArchiveWithScriptSnapshot".
+
+ January 15, 2018: Marked "initWithFLXArchive" and
+ "initWithFLXArchiveWithScriptSnapshot" as unavailable following the
+ deprecation from December 11, 2017. Scheduled to be removed on February
+ 19, 2018.
+
+ January 09, 2018: Deprecated "FlutterStandardBigInteger" and its use in
+ "FlutterStandardMessageCodec" and "FlutterStandardMethodCodec". Scheduled to
+ be marked as unavailable once the deprecation has been available on the
+ flutter/flutter alpha branch for four weeks. "FlutterStandardBigInteger" was
+ needed because the Dart 1.0 int type had no size limit. With Dart 2.0, the
+ int type is a fixed-size, 64-bit signed integer. If you need to communicate
+ larger integers, use NSString encoding instead.
+
+ December 11, 2017: Deprecated "initWithFLXArchive" and
+ "initWithFLXArchiveWithScriptSnapshot" and scheculed the same to be marked as
+ unavailable on January 15, 2018. Instead, "initWithFlutterAssets" and
+ "initWithFlutterAssetsWithScriptSnapshot" should be used. The reason for this
+ change is that the FLX archive will be deprecated and replaced with a flutter
+ assets directory containing the same files as the FLX did.
+
+ November 29, 2017: Added a BREAKING CHANGES section.

+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent

+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

+## Installation
+
+See the three subsections for details about three different installation methods.
+1. [Standard pod install](README.md#standard-pod-install)
+1. [Installing from the GitHub repo](README.md#installing-from-github)
+1. [Experimental Carthage](README.md#carthage-ios-only)
+
+### Standard pod install
+
+Go to
+[https://firebase.google.com/docs/ios/setup](https://firebase.google.com/docs/ios/setup).
+
+### Installing from GitHub
+
+For releases starting with 5.0.0, the source for each release is also deployed
+to CocoaPods master and available via standard
+[CocoaPods Podfile syntax](https://guides.cocoapods.org/syntax/podfile.html#pod).
+
+These instructions can be used to access the Firebase repo at other branches,
+tags, or commits.
+
+#### Background
+
+See
+[the Podfile Syntax Reference](https://guides.cocoapods.org/syntax/podfile.html#pod)
+for instructions and options about overriding pod source locations.
+
+#### Accessing Firebase Source Snapshots
+
+All of the official releases are tagged in this repo and available via CocoaPods. To access a local
+source snapshot or unreleased branch, use Podfile directives like the following:
+
+To access FirebaseFirestore via a branch:
+```
+pod 'FirebaseCore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
+pod 'FirebaseFirestore', :git => 'https://github.com/firebase/firebase-ios-sdk.git', :branch => 'master'
+```
+
+To access FirebaseMessaging via a checked out version of the firebase-ios-sdk repo do:
+
+```
+pod 'FirebaseCore', :path => '/path/to/firebase-ios-sdk'
+pod 'FirebaseMessaging', :path => '/path/to/firebase-ios-sdk'
+```
+
+### Carthage (iOS only)
+
+Instructions for the experimental Carthage distribution are at
+[Carthage](Carthage.md).
+
+### Rome
+
+Instructions for installing binary frameworks via
+[Rome](https://github.com/CocoaPods/Rome) are at [Rome](Rome.md).
+
+## Development
+
+To develop Firebase software in this repository, ensure that you have at least
+the following software:
+
+  * Xcode 10.1 (or later)
+  * CocoaPods 1.7.2 (or later)
+  * [CocoaPods generate](https://github.com/square/cocoapods-generate)
+
+For the pod that you want to develop:
+
+`pod gen Firebase{name here}.podspec --local-sources=./ --auto-open --platforms=ios`
+
+Note: If the CocoaPods cache is out of date, you may need to run
+`pod repo update` before the `pod gen` command.
+
+Note: Set the `--platforms` option to `macos` or `tvos` to develop/test for
+those platforms. Since 10.2, Xcode does not properly handle multi-platform
+CocoaPods workspaces.
+
+Firestore has a self contained Xcode project. See
+[Firestore/README.md](Firestore/README.md).
+
+### Development for Catalyst
+* `pod gen {name here}.podspec --local-sources=./ --auto-open --platforms=ios`
+* Check the Mac box in the App-iOS Build Settings
+* Sign the App in the Settings Signing & Capabilities tab
+* Click Pods in the Project Manager
+* Add Signing to the iOS host app and unit test targets
+* Select the Unit-unit scheme
+* Run it to build and test
+
+### Adding a New Firebase Pod
+
+See [AddNewPod.md](AddNewPod.md).
+
+### Code Formatting
+
+To ensure that the code is formatted consistently, run the script
+[./scripts/style.sh](https://github.com/firebase/firebase-ios-sdk/blob/master/scripts/style.sh)
+before creating a PR.
+
+Travis will verify that any code changes are done in a style compliant way. Install
+`clang-format` and `swiftformat`.
+These commands will get the right versions:
+
+```
+brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/e3496d9/Formula/clang-format.rb
+brew upgrade https://raw.githubusercontent.com/Homebrew/homebrew-core/7963c3d/Formula/swiftformat.rb
+```
+
+Note: if you already have a newer version of these installed you may need to
+`brew switch` to this version.
+
+To update this section, find the versions of clang-format and swiftformat.rb to
+match the versions in the CI failure logs
+[here](https://github.com/Homebrew/homebrew-core/tree/master/Formula).
+
+### Running Unit Tests
+
+Select a scheme and press Command-u to build a component and run its unit tests.
+
+#### Viewing Code Coverage
+
+First, make sure that [xcov](https://github.com/nakiostudio/xcov) is installed with `gem install xcov`.
+
+After running the `AllUnitTests_iOS` scheme in Xcode, execute
+`xcov --workspace Firebase.xcworkspace --scheme AllUnitTests_iOS --output_directory xcov_output`
+at Example/ in the terminal. This will aggregate the coverage, and you can run `open xcov_output/index.html` to see the results.
+
+### Running Sample Apps
+In order to run the sample apps and integration tests, you'll need valid
+`GoogleService-Info.plist` files for those samples. The Firebase Xcode project contains dummy plist
+files without real values, but can be replaced with real plist files. To get your own
+`GoogleService-Info.plist` files:
+
+1. Go to the [Firebase Console](https://console.firebase.google.com/)
+2. Create a new Firebase project, if you don't already have one
+3. For each sample app you want to test, create a new Firebase app with the sample app's bundle
+identifier (e.g. `com.google.Database-Example`)
+4. Download the resulting `GoogleService-Info.plist` and replace the appropriate dummy plist file
+(e.g. in [Example/Database/App/](Example/Database/App/));
+
+Some sample apps like Firebase Messaging ([Example/Messaging/App](Example/Messaging/App)) require
+special Apple capabilities, and you will have to change the sample app to use a unique bundle
+identifier that you can control in your own Apple Developer account.
+
+## Specific Component Instructions
+See the sections below for any special instructions for those components.
+
+### Firebase Auth
+
+If you're doing specific Firebase Auth development, see
+[the Auth Sample README](Example/Auth/README.md) for instructions about
+building and running the FirebaseAuth pod along with various samples and tests.
+
+### Firebase Database
+
+To run the Database Integration tests, make your database authentication rules
+[public](https://firebase.google.com/docs/database/security/quickstart).
+
+### Firebase Storage
+
+To run the Storage Integration tests, follow the instructions in
+[FIRStorageIntegrationTests.m](Example/Storage/Tests/Integration/FIRStorageIntegrationTests.m).
+
+#### Push Notifications
+
+Push notifications can only be delivered to specially provisioned App IDs in the developer portal.
+In order to actually test receiving push notifications, you will need to:
+
+1. Change the bundle identifier of the sample app to something you own in your Apple Developer
+account, and enable that App ID for push notifications.
+2. You'll also need to
+[upload your APNs Provider Authentication Key or certificate to the Firebase Console](https://firebase.google.com/docs/cloud-messaging/ios/certs)
+at **Project Settings > Cloud Messaging > [Your Firebase App]**.
+3. Ensure your iOS device is added to your Apple Developer portal as a test device.
+
+#### iOS Simulator
+
+The iOS Simulator cannot register for remote notifications, and will not receive push notifications.
+In order to receive push notifications, you'll have to follow the steps above and run the app on a
+physical device.
+
+## Community Supported Efforts
+
+We've seen an amazing amount of interest and contributions to improve the Firebase SDKs, and we are
+very grateful!  We'd like to empower as many developers as we can to be able to use Firebase and
+participate in the Firebase community.
+
+### tvOS, macOS, and Catalyst
+Thanks to contributions from the community, many of Firebase SDKs now compile, run unit tests, and work on
+tvOS, macOS, and Catalyst.
+
+For tvOS, checkout the [Sample](Example/tvOSSample).
+
+Keep in mind that macOS, Catalyst and tvOS are not officially supported by Firebase, and this
+repository is actively developed primarily for iOS. While we can catch basic unit test issues with
+Travis, there may be some changes where the SDK no longer works as expected on macOS or tvOS. If you
+encounter this, please [file an issue](https://github.com/firebase/firebase-ios-sdk/issues).
+
+During app setup in the console, you may get to a step that mentions something like "Checking if the app
+has communicated with our servers". This relies on Analytics and will not work on macOS/tvOS/Catalyst.
+**It's safe to ignore the message and continue**, the rest of the SDKs will work as expected.
+
+To install, add a subset of the following to the Podfile:
+
+```
+pod 'Firebase/ABTesting'
+pod 'Firebase/Auth'
+pod 'Firebase/Crashlytics'
+pod 'Firebase/Database'
+pod 'Firebase/Firestore'
+pod 'Firebase/Functions'
+pod 'Firebase/Messaging'
+pod 'Firebase/RemoteConfig'
+pod 'Firebase/Storage'
+```
+
+#### Additional Catalyst Notes
+
+* FirebaseAuth and FirebaseMessaging require adding `Keychain Sharing Capability`
+to Build Settings.
+* FirebaseFirestore requires signing the
+[gRPC Resource target](https://github.com/firebase/firebase-ios-sdk/issues/3500#issuecomment-518741681).

+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
