Fix DartDevelopmentServiceException

✅ Solution

DartDevelopmentServiceException often arises from inconsistencies or corruption within the Dart Development Service (DDS) cache or issues with DDS connecting to the running Flutter app. Try invalidating the caches and restarting your Flutter application by running "flutter clean" followed by a fresh build using "flutter run". If the issue persists, consider restarting your IDE or, in more severe cases, completely reinstalling the Flutter SDK.
