A collection of sample apps that demonstrate how Flutter can be used.
Each sample app is contained in a single
.dart file located in the
lib directory. To run each sample app, specify the corresponding file on the
flutter run command line, for example:
flutter run lib/animated_list.dart flutter run lib/app_bar_bottom.dart flutter run lib/basic_app_bar.dart ...
The apps are intended to be short and easily understood. Classes that represent the sample's focus are at the top of the file; data and support classes follow.
Each sample app contains a comment (usually at the end) which provides some standard documentation that also appears in the web view of the catalog. See the “Generating...” section below.
Markdown and a screenshot of each app are produced by
bin/sample_page.dart and saved in the
.generated directory. The markdown file contains the text taken from the Sample Catalog comment found in the app's source file, followed by the source code itself.
sample_page.dart command-line app must be run from the
examples/catalog directory. It relies on templates also found in the bin directory, and it generates and executes
test_driver apps to collect the screenshots:
cd examples/catalog dart bin/sample_page.dart
