【问题描述】：

这是我的小部件，用于在应用中显示我自己的小照片。

Widget image() 
    return CircleAvatar(
      radius: 50.0,
      backgroundImage: AssetImage('images/me.jpeg'),
    );
  

然而，出于某种原因，我不断收到这个

The following assertion was thrown resolving an image codec:
Unable to load asset: images/me.jpeg

When the exception was thrown, this was the stack: 
#0      PlatformAssetBundle.load (package:flutter/src/services/asset_bundle.dart:225:7)
<asynchronous suspension>
#1      AssetBundleImageProvider._loadAsync (package:flutter/src/painting/image_provider.dart:668:31)
#2      AssetBundleImageProvider.load (package:flutter/src/painting/image_provider.dart:651:14)
#3      ImageProvider.resolveStreamForKey.<anonymous closure> (package:flutter/src/painting/image_provider.dart:504:13)
...
Image provider: AssetImage(bundle: null, name: "images/me.jpeg")
Image key: AssetBundleImageKey(bundle: PlatformAssetBundle#14309(), name: "images/me.jpeg", scale: 1.0)

虽然图片在文件夹中。请帮忙

【问题讨论】：

您是否将图像路径添加到 pubspec.ymal 文件中？

【参考方案1】：

确保将图像添加到 pubspec.yaml 文件中，然后运行 ​​pub get

  assets:
    - images/me.jpeg
