在这里插入图片描述

• 修改pubspec.yaml文件
  
• 运行flutter run 又报错
  The current Flutter SDK version is 1.12.13+hotfix.9.

Because cached_network_image >=2.3.0-beta.1 <2.3.0-rc depends on flutter_cache_manager ^1.3.0 and cached_network_image >=1.1.2 <2.1.0 depends on flutter_cache_manager ^1.1.2, cached_network_image >=1.1.2 <2.1.0-∞ or >=2.3.0-beta.1 <2.3.0-rc requires flutter_cache_manager ^1.1.2.
And because cached_network_image >=2.1.0 <2.3.0-beta.1 depends on flutter_cache_manager ^1.2.0 and cached_network_image >=2.3.0-rc requires Flutter SDK version >=1.19.0-2.0.pre <2.0.0, cached_network_image >=1.1.2 requires flutter_cache_manager ^1.1.2.
So, because doubanapp depends on both flutter_cache_manager 1.1.0 and cached_network_image ^2.0.0-rc, version solving failed.
Running “flutter pub get” in FlutterDouBan…
pub get failed (1; So, because doubanapp depends on both flutter_cache_manager 1.1.0 and cached_network_image ^2.0.0-rc, version solving failed.)

• 可以看到cached_network_image版本更新后，与flutter_cache_manager版本起冲突，并且已经提示flutter_cache_manager版本更改1.1.2就可以了，
• 解决：
• 修改pubspec.yaml文件
  
• as中点击运行Pub get 重新获取包依赖或者手动运行flutter packages get 命令来下载依赖包。另外
