但是我的程序可以运行顺利，而且使用的sharedpreferences也很好用。我认为多次出现可以归因于我多次使用sharedPreferences。 shared_preference 依赖的版本是否专门针对此错误？
我的版本是： shared_preferences: ^0.4.2
谁能解决这个问题，谢谢。

早期版本可以手动初始化Doc:

const MethodChannel('plugins.flutter.io/shared_preferences')
  .setMockMethodCallHandler((MethodCall methodCall) async {
    if (methodCall.method == 'getAll') {
      return <String, dynamic>{}; // set initial values here if desired
    }
    return null;
  });

我在Flutter中使用sharedPreferences时，控制台反复报这样的bug？

When I use sharedPreferences in Flutter ,the console reported bugs like this repeatedly?
