QRResImage 遇到两个使用错误

[eleven-huang]

Hello,在使用时候碰到2个issue

一. 在使用QRResImage时候，我估计可能是依然react-dom版本低了
Error: Invalid hook call. Hooks can only be called inside of the body of a function component. This could happen for one of the following reasons:

1. You might have mismatching versions of React and the renderer (such as React DOM)
2. You might be breaking the Rules of Hooks
3. You might have more than one copy of React in the same app
   See https://fb.me/react-invalid-hook-call for tips about how to debug and fix this problem.

二. ReferenceError: window is not defined

在使用window前是否可以先判读下window是否已经加载了？

同时非常感谢，你们做的插件非常的棒。
