JetBrains IDE (IntelliJ) does not understand workspaces (always suggests to run pub get even when it's been run)

Tracking issue for dart-lang/sdk#56380 in the flutter/flutter-intellij bug repo.

[jwren]

Using the latest version of the Flutter IJ plugin, 2024.2, Flutter IJ plugin 242.20629, I get the following when I run dart pub get with the flutter/engine repository I am getting this error:

Because _engine_workspace depends on yaml from path which doesn't exist (could not find package yaml at "third_party/dart/third_party/pkg/yaml"), version
  solving failed.

And this error from the Dart IJ plugin:

java.lang.IllegalStateException: access contentManager when it's not yet available

To add onto this: Tests also always run flutter pub get before executing the tests as well, slowing down test execution.

To reproduce:

1. Create unit / widget test
2. Run test
3. See pub get executed
4. See results (pass / fail)
5. Run again
6. Pub get run again

@helin24 is this on track? We'd love workspaces to work also in intellij with the release of dart 3.6.
