The FocusManager constructor was registering global event handlers on the shared RawKeyboard instance and the global pointer router. This posed a few problems: (1) there was no way to unregister these handlers, and (2) instantiating a second FocusManager would overwrite the existing focus manager's RawKeyboard handler. This was manifesting in unexpected ways, such as the fact that constructing a second BuildOwner (for a parallel tree, for instance) was obliterating the event handler for the main BuildOwner's focus manager, thus messing with focus. This change separates those global event registrations into a dedicated method, registerGlobalHandlers(), and overrides dispose() to properly unregister those handlers.
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/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.
