We now use the `@required` annotation to encourage developers to explicitly set onPressed and onChanged callbacks to null when that would disable the widget. Fixes #287
Flutter Examples
This directory contains several examples of using Flutter. Each of these is an individual Dart application package.
To run an example, use flutter run inside that example's directory. See the
getting started guide to install
the flutter tool.
Available examples include:
-
Hello, world The hello world app is a basic app that shows the text "hello, world."
-
Flutter gallery The flutter gallery app showcases Flutter's implementation of material design.
-
Layers The layers vignettes show how to use the various layers in the Flutter framework. There is no main.dart in this directory because each file is a standalone example. To run a particular file, use
flutter run -t filename.dart.
