setState called after dispose

Users who leave this screen while saving cause a "setState() called after dispose()" error. What is the right fix?

Future<void> _save() async {
  await api.save(data);
  setState(() => _saved = true);
}

A.Wrap setState in try/catch and ignore all errorsB.Make _save synchronousC.Call super.dispose() first in dispose(), so the State stays alive until the save finishes and setState is safeD.Check if (!mounted) return; after the await and before calling setState
