当我运行 **flutter build apk --release ** 命令时，它不起作用并显示错误。
这是错误：
Font asset "MaterialIcons-Regular.otf" was tree-shaken, reducing it from 1645184 to
1352 bytes (99.9% reduction). Tree-shaking can be disabled by providing the --no-tree-shake-icons flag when building your app.

我搜索了很多，查看了所有与此主题相关的网站，并执行了他们所说的解决方案，但没有一个对我有用，我仍然遇到错误，这对我没有帮助。
我尝试了这些命令：
flutter build apk
flutter build apk --split-per-abi --no-tree-shake-icons
flutter build apk --no-tree-shake-icons
flutter build apk --release --no-tree-shake-icons
也可以，但不能再工作了。
如果您有解决方案，请帮忙。预先感谢
