flutter dart foo.dart to run dart foo.dart with FLUTTER_ROOT set

[kevmoo]

Required to run things like source_gen generators.

#13360 deals with pub run. This is just getting access to the dart command to run things not in the bin directory.

Here's the draft text I've included in json_serializable – which is pretty gnarly.

NOTE: If you're using Flutter, running a Dart script is a bit tricky. You can
find the Dart entry point at $FLUTTER_ROOT/bin/cache/dart-sdk/bin/dart.
You can determine FLUTTER_ROOT by looking at the first few lines of
flutter doctor.

Strawman: flutter cmd <path_to_cli_script> which simply runs the script via the same Dart version that is used in the engine (so the API in docs.flutter.io applies to scripts run via the Flutter cmd line. I don't want "two darts" for Flutter developers, there is one Dart for Flutter developers: the Dart that is documented on docs.flutter.io)

In the meantime, could source_gen ship a generic runner accessible from pub run ?

SGTM...

Sadly, no. We're working on a solution w/ pkg/build where there will be a common entry point. Hoping to have that nailed down in Q1.

Would a more idea solution be some way to register (maybe in pubspec.yaml, that flutter should execute some dart "script" during build? Then you wouldn't need to remember to manually run the generators?

[kevmoo]

That'd be good, too... We'd want to start talking about a real design at that point...

flutter packages pub run tool/build.dart does this currently.

[jonahwilliams]

Closing as pub can run dart scripts, and because we'll likely use a different solution for build_runner integration.

Also, note that I recently added passthrough for all pub commands, so the current shortest way of doing this is:

flutter pub run tool/build.dart
