Flutter - 无法在初始化程序中访问实例成员“remoteConfig”

Question

我试图在我的List 中调用remoteConfig 字符串

    class HomeModel {
      final RemoteConfig remoteConfig; //HomeModel() is called in Home() and fetches the param from there
      HomeModel({this.remoteConfig});
    
    List taskList = [
      { 
        'title': 'Hello',
        'url': remoteConfig.getString(''),
      },
    ];
}

但是，它向我显示了错误-

The instance member 'remoteConfig' can't be accessed in an initializer

Answer 1

将taskList的初始化移动到initState()。

List taskList;

@override
void initState() {
    taskList = [
      { 
        'title': 'Hello',
        'url': remoteConfig.getString(''),
      },
    ];
    super.initState();
}
