This attempts to reland #40186 and #41220, that were reverted in #41945. The main modifications from the original PRs are that I predefine the shortcuts and actions maps instead of defining them inline in the build function, and I use a new mapEquals to do a deep comparison so that we don't rebuild modified things if the contents of the map haven't changed. I also eliminated an operator== and hashCode that were defined on the Actions widget, since widgets shouldn't have those. (it's too bad though: I get an 85% speedup if we leave this in! Too bad it prevents rebuilding of the children...) Fixes #40101 |

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 showcases Flutter's widgets, including its implementation of material design.
-
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.
