当我运行' flutter build apk——release '时，flutter builder应用程序显示错误.

Question

嗨，我尝试用Android API 26平台输出我的apk，但当我运行flutter build apk --release时，它在终端显示错误，尽管我在构建中将targetSdkVersion和compileSdkVersion更改为26。gradle文件，也我的minSdkVersion是20.

here's error:

>flutter build apk --release

The build failed likely due to AndroidX incompatibilities in a plugin. The tool is about to try using Jetifier to solve the incompatibility.

Evenit works when i use API 29 in project structure.

Answer 1

尝试将compileSdkVersion更改为:

compileSdkVersion 28

fontVariationSettings添加到api级别28.
