Flutter can refresh data every time the interface comes in

Preface

Recently do flutter When the project is , I want to refresh data every time I enter my interface , Found a good way to use , Let's share with you ：

 @override
  Widget build(BuildContext context) {
    return VisibilityDetector(
      key: const Key('my-menu-key'),
      onVisibilityChanged: (VisibilityInfo visibilityInfo) {
        if (visibilityInfo.visibleFraction == 0.0) {
        } else {
          _getMemberInfo();
        }
      },
      child: Scaffold(
        backgroundColor: color_FFFFFFFF,
        body: Container(
          color: Colors.red,
        ),
      ),
    );
  }
  }

The key is VisibilityDetector, Then judge whether it is displayed , You can achieve your own effect ！
