为什么不能将简单图像添加到主页（Stless小部件）？

Question

在过去的几天里，我只是在尝试Flutter。我正在尝试添加图像，但根本不会显示。 我缺少明显的东西吗？

main.dart

with tempfile.NamedTemporaryFile(mode='wt', dir=F"{os.path.dirname(os.path.dirname(os.path.realpath(__file__)))}/assets/fetch/", delete=False, suffix=".xml") as fp:
        fp.write(generate_xml(param))
        from time import sleep
        sleep(.05)

        MODEL_PATH = fp.name
    model = mujoco_py.load_model_from_path(MODEL_PATH)

和我的pubspec.yaml

import 'package:flutter/material.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'PicHuntingNigga',
      home: Scaffold(
        appBar: AppBar(
          title: Text('PicHunting-Nigga'),
          centerTitle: true,
          backgroundColor: Colors.red,
        ),
        body: new Center(
          child: new MyCameraWidget(),
        ),
      ),
    );
  }
}

class MyCameraWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    var assetImage = new AssetImage('assets/images/camera1.png');
    var image = new Image(image: assetImage, width: 225.0, height: 225.0);
    return new Container(child: image);
  }
}

我的文件夹结构

运行模拟器后-所有内容都会减去图片。我可以将图像替换为name: flutter_app description: A new Flutter application. # https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html version: 1.0.0+1 environment: sdk: ">=2.1.0 <3.0.0" dependencies: flutter: sdk: flutter cupertino_icons: ^0.1.2 dev_dependencies: flutter_test: sdk: flutter flutter: uses-material-design: true assets: - assets/images/camera.png - assets/images/camera1.png - assets/images/ 子级，它将呈现文本，但不呈现图像。

另请参见此处示例https://flutter.dev/docs/development/ui/assets-and-images

Widget build(BuildContext context) {
  // ...
  return DecoratedBox(
    decoration: BoxDecoration(
      image: DecorationImage(
        image: AssetImage('images/background.png'),
        // ...
      ),
      // ...
    ),
  );
  // ...
}

所以我解决了！

不确定如何...。我刚刚关闭笔记本电脑，然后再打开。我也吃过晚饭，现在可以了。

所以，如果您遇到类似的问题，请共进晚餐？看来这对我来说是解决方案。
