Flutter ImageProvider错误-颤振

我遇到了一个图像提供商的bug，我目前正试图修复它（我是一个新手）。 我得到的错误是这样的

name: timeApp
description: A new Flutter project.

https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html
version: 1.0.0+1

environment:
  sdk: ">=2.7.0 <3.0.0"

dependencies:
  flutter:
    sdk: flutter


  cupertino_icons: ^0.1.3

dev_dependencies:
  flutter_test:
    sdk: flutter

flutter:

  # To add assets to your application, add an assets section, like this:
  assets:
    - assets/

../../flatter/packages/flatter/lib/src/painting/image_provider.dart:672:7:错误：应为标识符，但得到“/”。 /2雷思罗； ^

../../flatter/packages/flatter/lib/src/painting/image_provider.dart:672:8:错误：应为“；”在这之后。 /2雷思罗； ^

失败：生成失败，出现异常

我曾尝试使用

flatter clean

修复它，但这并不能解决问题NB我有包含图像的资源目录

main.dart看起来像

import 'package:flutter/material.dart';

void main() => runApp(MaterialApp(
  home: Home(),
));

class Home extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
          title: Text('my first app'),
          centerTitle: true,
          backgroundColor: Colors.red[600]
      ),
      body: Center(
        child: Image.asset('assets/2.jpg'),
      ),
      floatingActionButton: FloatingActionButton(
        backgroundColor: Colors.red[600],
        child: Text('click'),
      ),
    );
  }
}

pubspec.yaml看起来像这样
