Command line developer tools for building Flutter applications.
Be sure to follow the instructions on CONTRIBUTING.md to set up your development environment.
First, ensure that the Dart SDK and other necessary artifacts are available by invoking the Flutter Tools wrapper script. In this directory run:
$ ../../bin/flutter --version
To run Flutter Tools from source, in this directory run:
$ ../../bin/cache/dart-sdk/bin/dart bin/flutter_tools.dart
followed by command line arguments, as usual.
To run the analyzer on Flutter Tools, in this directory run:
$ ../../bin/flutter analyze
To run the tests in the test/ directory, first ensure that there are no connected devices. Then, in this directory run:
$ ../../bin/cache/dart-sdk/bin/pub run test
The tests in test/integration.shard are slower to run than the tests in test/general.shard. To run only the tests in test/general.shard, in this directory run:
$ ../../bin/cache/dart-sdk/bin/pub run test test/general.shard
To run the tests in a specific file, run:
$ ../../bin/cache/dart-sdk/bin/pub run test test/general.shard/utils_test.dart
When running all of the tests, it is a bit faster to use build_runner. First, set FLUTTER_ROOT to the root of your Flutter checkout. Then, in this directory run:
$ ../../bin/cache/dart-sdk/bin/pub run build_runner test
This is what we do in the continuous integration bots.
To force the Flutter Tools snapshot to be regenerated, delete the following files:
$ rm ../../bin/cache/flutter_tools.stamp ../../bin/cache/flutter_tools.snapshot
