我正在使用 flutter Riverpod（State Notifier Provider）进行状态管理。当我更新状态时，消费者小部件不会重建自身，因此即使我的状态正在更新，UI 也不会更新。我无法调试原因。

Pubspec.yaml

   flutter_riverpod: ^0.14.0+3

Riverpod StateNotifier 提供商

    final dataListModelProvider=StateNotifierProvider((ref)=>ExampleProvider ([]));

供应商

  class ExampleProvider extends StateNotifier<List<Example>>{

     ExampleProvider (List<Example> state):super(state ?? []);

     void createExample(Map exampleData) async{
     try{
        var response= await ExampleDao().createExampleData(exampleData);      // API request - working fine( All the data is coming back from API as expected)
       print(" ===== CREATED EXAMPLE TYPE===========");
       Example example=response;
       List<Example> listExampleData= [...state,example];
       print("========== INITIAL STATE =============Count = ${state.length}");
       print(state);
       state=listExampleData;
       print("========== UPDATED STATE =============Count = ${state.length}");
       print(state);
     }
    }catch(error,stackTrace){
         print(error);
         print(stackTrace);
      } …
