无法在Dio库中的onSendProgress内执行setState

class MyState with ChangeNotifier {
  double _progress = 0.0;

  double get progress => _progress;

  void updateProgress(double value) {
    _progress = value;
    notifyListeners();
  }
}

ChangeNotifierProvider(
  create: (context) => MyState(),
  child: YourWidget(),
)

final dio = Dio();
final myState = Provider.of<MyState>(context, listen: false);

dio.interceptors.add(InterceptorsWrapper(
  onRequest: (options, handler) {
    options.onSendProgress = (sent, total) {
      double progress = sent / total;
      myState.updateProgress(progress);
    };
    return handler.next(options);
  },
));

// 发起网络请求

Consumer<MyState>(
  builder: (context, myState, _) {
    return Text('Progress: ${myState.progress.toStringAsFixed(2)}');
  },
)
