The models' case: Best default for typical Flutter teams: first-party FlutterFire integration, automatic native iOS/Android crash capture, Dart fatal/non-fatal reporting, ANRs, solid. The models' main caveat: Debugging context is shallower than the best full observability tools. The strongest alternative is Sentry — Offers the deepest Flutter-specific observability available, providing seamless multi-layer stack trace symbolication across Dart AOT, C/C++ engine. Not unanimous: Gemini picks Sentry.
