Have implemented common permission_handler control.

Output from Chrome:

Sample Usage Code:

import flet as ft


def main(page: ft.Page):
    page.scroll = ft.ScrollMode.ADAPTIVE
    page.add(ft.SafeArea(ft.Text("PermissionHandler test")))
    ph = ft.PermissionHandler()
    page.overlay.append(ph)
    page.update()

    async def on_check_permission(e):
        page.add(ft.SafeArea(ft.Text(await ph.microphone.check_permission_async())))

    check_permission_button = ft.TextButton(
        "Check Permission", on_click=on_check_permission
    )

    async def on_request_permission(e):
        page.add(ft.SafeArea(ft.Text(await ph.microphone.request_permission_async())))

    request_permission_button = ft.TextButton(
        "Request Permission", on_click=on_request_permission
    )
    page.add(
        ft.SafeArea(check_permission_button), ft.SafeArea(request_permission_button)
    )


ft.app(main)
