Flutter Android SDK版本28错误，但我正在使用30 [英] Flutter Android SDK version 28 Error but I am using 30

问题描述

当我创建一个新的flutter应用程序时，它将启动android sdk版本28，但我使用的是android sdk 30.Flutter医生还展示了Android平台-30，构建工具30.0.2.当我尝试安装url_launcher或shared_preferences之类的软件包时，出现错误，它查找的是Android SDK 30.同样，每次我从build.gradle更改android sdk verison时.

When I create a new flutter app, It starts android sdk version 28 but I use android sdk 30. Flutter doctor also shows Platform android-30, build-tools 30.0.2. When I tried to install a package like url_launcher or shared_preferences I am getting error It looks for Android sdk 30. Also every time I am changing android sdk verison from build.gradle.

这是我扑扑的医生的输出:

Here is My flutter doctor output:
