• I have searched the existing issues

Current Behavior

https://live.douyin.com/
在页面后，刚开始是正常工作的，但几秒后程序就没有预兆的直接闪退了
Open a specific website:

https://www.douyin.com/

At the back of the page, it initially worked normally, but after a few seconds, the program crashed without warning

Expected Behavior

It is caused by missing implementation of onPermissionRequest event on Flutter side. Implementing it, you should workaround the current crash.
it should be fixed on next version 6.2.0-beta.2.
