I'm very in trouble and want to help.

When I use Provider(not MultiProvider), Could not find the correct Provider<LaborModel>is not happend and works correctly.
However when I use MultiProvider, the error was happen.

I have already ensured the Provider is an ancestor to this Consumer Widget.

my source Excerpt

        providers: [
          ChangeNotifierProvider<RewordModel>(create: (_) => RewordModel()),
          ChangeNotifierProvider<LaborModel>(create: (_) => LaborModel()),
          ChangeNotifierProvider<PointModel>(create: (_) => PointModel()),
        ],

my source Excerpt

  Widget build(BuildContext context) {
    return Consumer<LaborModel>(builder: (context, laborModel, child) {
      return Scaffold(
        body: ListView.builder(
          itemBuilder: (BuildContext context, int index) {
            return Card(
              child: Padding(
                child: Text(
                  laborModel.rewardList[index].point.toString() + " Point:　　" + laborModel.rewardList[index].name,
                  style: TextStyle(fontSize: 22.0),
                ),
                padding: EdgeInsets.all(20.0),
              ),
            );
          },
          itemCount: laborModel.rewardList.length,
        ),
      );
    });
  }
