Flutter test stucks at `"event":"test.startedProcess"` when running it from `Run` button

[huycozy]

I encounter this on Android Studio IDE while it works well on VS Code IDE.

Steps to reproduce

1. Click on Run button on the left of the test
2. Observe the run output and see it's stuck as the output log follows:

[{"event":"test.startedProcess","params":{"vmServiceUri":"http://127.0.0.1:62047/VFPfi0PrluM=/"}}]

The test only stuck if I ran the test from IDE's UI with Run button, but it's successful when running with CLI in terminal:

➜  flutter git:(master) ✗ fpr test /Users/huym4/Documents/WORKING/SDK/flutter_pr/packages/flutter/test/material/page_transitions_theme_test.dart

flutter doctor -v
