插件版本旧，不能使用插件新特性
如 flutter_screenutil库

看到这个功能的更新：ExceptionBinding，使viewModel可以对内部的所有api接口的异常捕获

目前我的view model实现了ExceptionBinding的notifyException方法以及监听者注册，但是看了框架代码之后，没发现在什么地方来调用注册的监听。麻烦能不能解释一下？谢谢了大佬!!

注：
1.只在exception_pitcher.dart中看到view model InitData()的异常状态捕获
2.未看到其他地方对非initData()的api异常监听回调使用

suggest:
make loading widget global, such as EasyLoading

The plugins flutter_custom_dialog, launch_review, open_file, share use a deprecated version of the Android embedding.
To avoid unexpected runtime failures, or future build failures, try to see if these plugins support the Android V2 embedding. Otherwise, consider removing them since a future release of Flutter will remove these deprecated APIs.
If you are plugin author, take a look at the docs for migrating the plugin to the V2 embedding: https://flutter.dev/go/android-plugin-migration.

在BaseState里面的show对话框，我看到是直接push一个页面，什么都好，就是没处理好返回键的时候，只要show之后按下返回键，就再也show不出来了

请问最新版的代码，flutter版本、androidstudio版本、dart版本分别是多少啊。我这里运行不起来
我分别用了flutter2.8.1最新的，flutter2.0.0,flutter2.5.3.androidsutdio版本是最新的，都运行不起来。
