setState() called after dispose()

[II11II]

App error: setState() called after dispose(): _VitalityState#eee0e(lifecycle state: defunct, not mounted)

The timer is not cancelled after state is disposed
Please add this line inside _VitalityState

  void dispose() {
    timer.cancel();
    super.dispose();
  }
