Extract substring not working with JetBrains Dart Plugin

[StephenBrough]

When I select a substring and try either Ctrl+Alt+V, or bring up the refactor menu with Ctrl+Alt+Shift+T and select 'Introduce Variable', nothing happens. I tried both Android Studio and IntelliJ with the Dart plugin. This extraction operation does work in VSCode.

I don't know exactly where this issue may be coming from, a comment on this issue suggests an issue with the analysis server.

I'm not super familiar with the flow of how things work, but I pulled down the Dart SDK, added some logs at various points in extract_local.dart, and everything appears to be working. Unless I missed something, I'm not seeing anything reporting a fatal status. I don't see createChange() being called, seems like the IDE should be calling that at some point.

I don't see any logs from Android Studio/IntelliJ, seems to just silently fail.

To reproduce, just have any kind of local String and try extracting the sub string from it.

void main(List<String> arguments) {
  final stringTest = 'Hello Chris, welcome back';
}
