错误信息： This application cannot tree shake icons fonts. It has non-constant instances of IconData at the following locations:

• file:///Users/cinson/.pub-cache/hosted/pub.flutter-io.cn/fair_version-3.0.0+2/lib/src/widgets/$$w.dart:3648:30 FAILURE: Build failed with an exception.

暂时加上--no-tree-shake-icons规避了一下，但是还是fair本身要解决一下这个问题

目前fair动态化是通过解析JOSN节点在运行时创建Widget的方式实现的，所以创建的Widget的参数都是在运行时才确定，这也导致创建的widget无法声明为const。这个问题我们在后续会想办法做兼容处理，现阶段只能通过--no-tree-shake-icons规避
