context property

Implementation

BuildContext get context {
  assert(() {
    if (_element == null) {
      throw StateError(
          'This widget has been unmounted, so the State no longer has a context (and should be considered defunct). \n'
          'Consider canceling any active work during "dispose" or using the "mounted" getter to determine if the State is still active.');
    }
    return true;
  }());
  return _element!;
