flutter-handling-concurrency

Runs heavy computations in background Dart isolates so the Flutter UI stays responsive. Covers the decision between async/await for I/O tasks and Isolate.run or Isolate.spawn for CPU-bound work, with patterns for both short-lived and long-lived worker isolates. Gives you a clear decision framework and ready-to-use isolate patterns instead of guessing when async/await stops being enough and actual threading is needed.
