This moves the app template more toward being a more generic starting point for any Flutter application, eliminating some hard-code assumptions about there being a single window/engine pair that is directly bound to the life of the application: - Moves the runloop into its own class, making it capable of servicing any number of engine instances. - Moves the logic for setting up a window containing only a Flutter view into a window subclass for ease of re-use. - Makes quit-on-window-close an optional property. (Long term this should be even more generic, like a quit-when-last-window-closes option, but this is a short-term improvement that removes the binding between the runloop and the window). - Allows for multiple instances of Win32Window to exist without issues relating to the window class registration. Since there are getting to be a non-trivial number of files associated with the runner, this moves the source into a runner/ directory, as is already done on some other platforms. Note that creating multiple Flutter windows at the same time still doesn't work correctly even with this change, but this addresses some of the known issues, and makes it easier to test in the future (e.g., for debugging engine-level issues with multiple instances). Fixes #45397
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.
