flutter drive Impeller startup crashes appear as VM HTTP exceptions #162087
Description
Reproduction:
- Start an Android 34 emulator
- Use the following
AndroidManifest.xmlto forcevulkan(i.e. no fallback logic), though other crashes might also cause this - Try running the app with
flutter drive lib/main.dart
You'll get something like:
$ flutter drive lib/main.dart
It is taking an unusually long time to connect to the VM...
Oops; flutter has exited unexpectedly: "HttpException: Connection closed before full header was receivedThere are two bugs:
- We are missing information on why we can't connect (more on that in a second)
- The crash has nothing to do with the VM service or HTTP
If you flutter run lib/main.dart (i.e. the same code, just with flutter run):
$ flutter run lib/main.dart
