• I have searched for answers to my question both in the issues and in previous discussions.

Flet has webview contol already see. It is supports iOS and Android only; a desktop and browser versions are in the development.

Besides that like as the code says webview must be in the main thread which is not possible due flet (Flet works on main thread)
You can access the main thread object using the current_thread() method from the threading module.

I couldn't find a solution 🙃

And i am not sure but adding something visible to gui you need to use flet controls not another gui modules
