I had resolved the issues by upgrading to the latest Flutter SDK version 3.3.2.

Actually in Flutter SDK ,If you find the file changenotifier.dart file. at this location /Users/sumitjaiswal/Desktop/flutter/packages/flutter/lib/src/foundation

You will find this code .

static bool debugAssertNotDisposed(ChangeNotifier notifier) {
    assert(() {
      if (notifier._debugDisposed) {
        throw FlutterError(
          'A ${notifier.runtimeType} was used after being disposed.\n'
          'Once you have called dispose() on a ${notifier.runtimeType}, it '
          'can no longer be used.',
        );
      }
      return true;
    }());
    return true;
  }

This has changed from dfg throw to throw. So,I had just upgrade to latest version of Flutter SDK 3.3.2.
