Describe the bug

TL;DR I can't evaluate code in Debug Console when running integration tests. I don't know if I'm doing something wrong or if this is just not possible.

Also, I can't find a way to run (using VS Code's launch.json) normal widget tests with flutter run test/widget_test.dart (=running on device) instead of flutter test test/widget_test.dart (running in isolation). This might be another issue, though.

To Reproduce

TL;DR Run any Flutter integration test with VS Code and try to evaluate Dart code in the Debug Console.

Create .vscode/launch.json in the root of a Flutter project with the following contents:

{
  "version": "0.2.0",
  "configurations": [
    {
      "name": "flutter run app",
      "request": "launch",
      "type": "dart",
      "program": "lib/main.dart"
    },
    {
      "name": "flutter run integration tests",
      "request": "launch",
      "type": "dart",
      "program": "integration_test/example_test.dart"
    },
  ]
}

1. Clone the repository of the Patrol framework
2. Open the example app directory with VS Code ($ code .). It's located in packages/patrol/example
3. Now that you're in the example app's dir, put a breakpoint somewhere in the integration_test/example_test.dart file, for example on line 16:

   await $(FloatingActionButton).tap();

4. Run the flutter run integration tests configuration from launch.json
5. Try to evaluate some code in the Debug Console.
6. See _compileExpression: No compilation service available; cannot evaluate from source..

Expected behavior

Being able to evaluate Dart code in Debug Console when the test is stopped on a breakpoint.

This is how it works with widget tests running in isolation:
