useWebview

Currently we are building a "idk i call it handler 😂" for handling certain actions regarding the webview
we'll surely expand it by time but here are some existing methods you'll be able to use soon

import {useWebview} from './useWebview' // Client

const Webview = useWebview();

Webview.page // string - this is the same as Webview.currPage
Webview.pages // string[] - existing pages
Webview.currPage // string - current page
Webview.isFocused // boolean  - whether the webview is focused or not
Webview.setPage("pageNameInRouter") // set the page and our router will directly route to the page
Webview.focus() // sets the focus to the webview
Webview.focused() // returns the Webview.isFocused value
Webview.unfocus() // checks if the nui is focused and sets the focus to false
