颤振错误：LateInitializationError：字段“计数”尚未初始化

我收到此错误：小部件库 LateInitializationError 捕获的异常：字段“计数”尚未初始化。相关的导致错误的小部件是 Consumer lib\...\views\base_view.dart:31

我该如何解决这个错误？谢谢 ？

import 'package:provider/provider.dart';

import '../../locator.dart';

class BaseView<T extends ChangeNotifier> extends StatefulWidget {
  final Widget Function(BuildContext context, T value, Widget? child) builder;
  final Function(T)? onModelReady;

  BaseView({required this.builder, required this.onModelReady});

  @override
  _BaseViewState<T> createState() => _BaseViewState<T>();
}

class _BaseViewState<T extends ChangeNotifier> extends State<BaseView<T>> {
  T model = locator<T>();

  @override
  void initState() {
    if (widget.onModelReady != null) {
      widget.onModelReady!(model);
    }
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    return ChangeNotifierProvider<T>(
      create: (context) => model,
      child: Consumer<T>(builder: widget.builder),
    );
  }
}```
