Flutter项目中Image.asset加载图片失败问题求助

问题详情 #

使用的代码片段 #

Padding(
  padding: const EdgeInsets.only(left: 80, right: 80),
  child: Image.asset('assets/images/logo.png'),
),

文件结构 #

图片实际存放路径为 lib/assets/images/logo.png

pubspec.yaml配置 #

assets:
- lib/assets/images/
- lib/assets/images/logo.png

报错信息 #

════════ Exception caught by image resource service ════════════════════════════
The following assertion was thrown resolving an image codec:
Unable to load asset: assets/images/logo.png.

...（省略中间栈信息）

Image provider: AssetImage(bundle: null, name: "assets/images/logo.png")
Image key: AssetBundleImageKey(bundle: PlatformAssetBundle#3359f(), name: "assets/images/logo.png", scale: 1.0)
════════════════════════════════════════════════════════════════════════════════

解决步骤 #

1. 修正代码中的资源路径
   代码引用路径必须和pubspec.yaml配置的路径完全匹配，修改后代码如下：

   Padding(
     padding: const EdgeInsets.only(left: 80, right: 80),
     child: Image.asset('lib/assets/images/logo.png'),
   ),
   

2. 检查pubspec.yaml格式正确性
   确保assets配置在flutter节点下，缩进符合YAML要求（通常为2个空格），正确格式示例：

   flutter:
     uses-material-design: true
     assets:
       - lib/assets/images/
       - lib/assets/images/logo.png
   

3. 刷新资源并重启应用
   执行命令 flutter pub get 刷新资源配置，然后完全重启应用（热重载可能不生效，需冷启动）。
