bugstweet 0.9.4

Testers report bugs from inside your Flutter app as GitHub issues an AI coding agent can fix. Tester builds only: store builds never contain it.

example/lib/main.dart

// The sample app: a tiny health tracker with two planted bugs.
//
// This is the "store build" entry point. It knows nothing about bugsTweet.
// See .bugstweet/tester.dart for the tester build.
