return 类型不是闭包上下文所要求的小部件

Question

我尝试完成教程，但出现此错误（查看图片）。

import 'package:flutter/material.dart';
import 'package:provider/provider.dart';
import 'package:provider_architecture/core/viewmodels/login_model.dart';
import 'package:provider_architecture/locator.dart';

class LoginView extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return ChangeNotifierProvider<LoginModel>(
      builder: (context) => locator<LoginModel>(), // the error is here
      child: Consumer<LoginModel>(
        builder: (context, model, child) => Scaffold(),
      ),
    );
  }
}

Answer 1

变化：

builder: (context) => locator<LoginModel>()

至：

create: (context) => locator<LoginModel>()

return 类型不是闭包上下文所要求的小部件

The return type isn't a widget as required by the closures context

provider
