Problem when running flutter app with isolates on disconnected android phone #4066
Description
Describe the bug
When using the VSCode extension to start flutter applications on android devices without debugging and then disconnecting the android device it seems that isolates are not started properly anymore.
The following line of code in the provided example app is not being executed anymore:
await compute(mockJob, null);When running the same app simply with flutter run everything works as expected.
To Reproduce
Steps to reproduce the behavior:
- Checkout this example flutter app.
- Connect an android device via USB.
- Run the example app with VSCode Flutter + Dart extension in mode "Run without debugging".
- After the app starts disconnect the USB.
- Click on the button "press" in the app and see nothing happens.
Note, providing logs is a bit hard because when the device stays connected to USB and attached then the problem doesn't occur.
Expected behavior
When pressing the "press" button the text should change.
Note, the behavior works as expected when running the app with the command flutter run in debug or not debug mode.
Screenshots
