flutter_tester hangs on linux workstation #19273
Description
On my Linux workstation, running flutter tester just hangs and doesn't find a flutter view to run on.
Repro:
flutter create mytestcd mytestflutter run -d flutter-tester --verbose- fails with a stack trace and
Error connecting to the service protocol: Exception: No Flutter view is available
The same thing works fine on my mac, and flutter tester tests seem to run fine on the bots.
I have tried:
- killing all flutter_tester processes (there were 10 running! I think it's not dying properly either).
- rebooting my machine
- nuking my cache directory and git pulling from master again.
- running flutter_tester manually directly. It runs and just sits there not reporting any errors.
I'm using master branch HEAD at 36e16e7.
Here's the entire output:
