即使缩进正确也无法加载

Question

它给出了无法加载资产的错误

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        backgroundColor: Colors.teal,
        body: SafeArea(
          child: Column(
            children: <Widget>[
              CircleAvatar(
                radius: 50.0,
                backgroundImage: AssetImage("images/rishi.jpg"),
              ),
            ],
          ),
        ),
      ),
    );
  }
}

即使我检查了 pubspec 文件的缩进，它也会给我错误...附在下面

flutter:

 
  uses-material-design: true

  
  assets:
    - images/rishi.jpg

将新资源附加为资产后，需要在热重载之前进行冷启动。否则会报错。
