二、问题分析

找不到方法 , 怀疑是使用了落后的 Flutter SDK 版本 , 这里更新到最新的测试版本 ;

三、解决方案

下载 2.1.0-12.2.pre 版本的 Flutter SDK ;

flutter_windows_2.1.0-12.2.pre-beta.zip

下载后解压上述 SDK 压缩包 flutter_windows_2.1.0-12.2.pre-beta.zip ;

解压后的 Flutter SDK 路径为 : Y:\001_DevelopTools\010_Flutter\flutter_windows_2.1.0-12.2.pre-beta\flutter ;

在 " File / Settings / Languages & Frameworks / Flutter " 下配置最新版本的 Flutter SDK 路径 ;

Y:\001_DevelopTools\010_Flutter\flutter_windows_2.1.0-12.2.pre-beta\flutter

在 " File / Settings / Languages & Frameworks / Dart " 下配置最新版本的 Dart SDK 路径 ;
