CP of https://github.com/flutter/flutter/pull/170490 This PR rolls back auto-migrating iOS apps to UIScene lifecycle. It also updates tests to ensure things work in both a state where UIScene lifecycle is already adopted and when it isn't. A number of UIScene issues have emerged since landing this in master: https://github.com/flutter/flutter/issues/170171 In addition, there's is disagreement over how some of it is implemented. Impacted Users: All Flutter iOS developers Impact Description: Some method channels may crash and apps using app lifecycle events may not work properly. Workaround: Manually removing UIApplicationSceneManifest from Info.plist and potentially also update AppDelegate.swift. Risk: Low Test Coverage: Yes Validation Steps: Run `flutter build ios` and see that `UIApplicationSceneManifest` if not added to Info.plist.
Flutter Examples
This directory contains several examples of using Flutter. To run an example,
use flutter run inside that example's directory. See the getting started
guide to install the flutter tool.
For additional samples, see the
flutter/samples repo.
Available examples include:
-
Hello, world The hello world app is a minimal Flutter app that shows the text "Hello, world!"
-
Flutter gallery The flutter gallery app no longer lives in this repo. Please see the gallery repo.
-
Layers The layers vignettes show how to use the various layers in the Flutter framework. For details, see the layers README.
-
Platform Channel The platform channel app demonstrates how to connect a Flutter app to platform-specific APIs. For documentation, see https://flutter.dev/to/platform-channels/.
-
Platform Channel Swift The platform channel swift app is the same as platform channel but the iOS version is in Swift and there is no Android version.
Notes
Note on Gradle wrapper files in .gitignore:
Gradle wrapper files should normally be checked into source control. The example projects don't do that to avoid having several copies of the wrapper binary in the Flutter repo. Instead, the Gradle wrapper is injected by Flutter tooling, and the wrapper files are .gitignore'd to avoid making the Flutter repository dirty as a side effect of running the examples.
