1，在项目根目录下打开 pubspec.yaml 文件，找到如下代码，添加高亮处代码dependencies: flutter: sdk: flutter # The following adds the Cupertino Icons font to your application. # Use with the CupertinoIcons class for iOS style icons. cupertino_icons: ^0.1.2 english_words: ^3.1.0
2，在 AS 命令行中执行flutter packages get即可
3，此时依旧报错的话，重启android studio 即可
