我是新来的Flutter Riverpod management

我使用 stfl 小部件Flutter Riverpod management，我需要将 test bool 变量更改为 true 但无法处理它

final testProvider = StateProvider<bool>((ref) => false);

    !test ? Text('bool varible is false')
                         :  Text('bool varible is true')
     FutureBuilder(
           future: FirebaseFirestore.instance.collection('users')
                      .doc('userId').get(),
            builder: (context, AsyncSnapshot snapshot) {
               if(!snapshot.hasData){
                     return …
