`dart:mirrors` dependencies block this from being used in a Flutter app
CareF opened this issue · comments
As long as an app import 'package:metrics_center/flutter.dart';, when doing flutter drive/run --profile it will show:
error: import of dart:mirrors is not supported in the current Dart runtime
Dart snapshot generator failed with exit code 254

It seems that this package is implicitly depending on dart:mirrors which is not compatible with flutter's dart runtime.
debug mode will let the app start but not fully functioning, with a different error message:
E/flutter (30963): [ERROR:flutter/shell/common/shell.cc(210)] Dart Error: error: import of dart:mirrors is not supported in the current Dart runtime
E/flutter (30963): [ERROR:flutter/shell/common/engine.cc(205)] Could not prepare to run the isolate.

With https://pub.dev/packages/import_path and
pub global activate import_path
pub global run import_path lib/flutter.dart dart:mirrors
it turns out to be gcloud/db.dart
Remove myself from the assignment as I'm not actively working on this. Will reassign myself once I get some time to work on it.
Closing this as our newest plan is to remove dependency on gcloud/db.dart (datastore) and only depend on gcloud/storage.dart. I just ran pub global run import_path lib/skiaperf.dart dart:mirrors and confirmed that gcloud/storage.dart doesn't depend on dart:mirrors:
Unable to find an import path from file:///Users/liyuqian/flutter/flutter/dev/benchmarks/metrics_center/lib/src/skiaperf.dart to dart:mirrors
