flutter,android打包IconData报错

话不多说，直接上错误，This application cannot tree shake icons fonts. It has non-constant instances of IconData at the following locations:

• file:///Users/mac/workSpace/03_AndroidStudioProject/newsinenglish/lib/common/loading/loading_widget.dart:120:13 FAILURE: Build failed with an exception.
  • Where:
  • Script '/Users/mac/workSpace/02_development/flutter/packages/flutter_tools/gradle/flutter.gradle' line: 896
  • What went wrong:
  • Execution failed for task ':app:compileFlutterBuildRelease'.

Process 'command '/Users/mac/workSpace/02_development/flutter/bin/flutter'' finished with non-zero exit value 1错误截图如下：

解决方法：

1.用命令 flutter build apk --no-tree-shake-icons 来打包，（不过这个方法不建议，因为以后都不能用菜单中的Build Apk来打包了。。。）

2.在IconData之前加上const；

3.直接换掉IconData中的图片（阿里妈妈网站的图片索引），用本地图片的加载方式去显示图片。
