Code Review
This pull request adds exit code verification for Flutter processes in hot mode tests and introduces a helper function to retrieve and print JVM crash logs upon failure. Feedback suggests documenting the new function according to the style guide and adding error handling to the log retrieval logic to prevent masking the original process failure.
