Question

我决定将流程集成到我的项目中，无法解决一些类型错误。我进行了很多搜索，但找不到以下值的类型。

例如

参考类型
用于构造道具的类型
this.localNotifications（变量）的类型
绑定方法时如何定义类型。

我在下面共享我的代码，但遇到错误。预先感谢

如果您检查构造函数的代码，会发现许多变量和引用都被使用。我仍然想描述每个错误，这将有助于理解

道具缺少类型注释。（对于构造器道具）



无法将React.createRef（）分配给this.passwordRef，因为Login [1]中缺少属性passwordRef



无法将this.updateInfo.bind（...）分配给this.updateInfo，因为属性updateInfo是不可写的。



无法为this.localNotification分配新的LocalNotification（），因为Login [1]中缺少属性localNotification

无法解决反应器中某些类型的流量误差
