Proposal

patrol_cli should generate gradlew on its own when there isn't one.

[bartekpacia]

This problem is already fixed in Flutter. See flutter/flutter#121904. It's not available on the stable channel yet, and won't be until the next major Flutter release (usually ~3 months).

Before it becomes available, you have to manually run flutter build apk --debug --flavor does-not-exist || true. The bad thing is that it actually tries to build the app, so it is slow.

When that PR is on the stable channel, to generate the gradlew file you'll do flutter build apk --config-only. It's very fast, just like flutter build ios --config-only, which has been available for a few years now.

For anyone arriving at this issue more recently: the fix has arrived on Flutter stable, so you can do:

flutter build apk --config-only
