Hi, you need to call pick_files_dialog.pick_files_async as an action on button click. Since it's an async function you can't use lambda, so try:

...
    async def show_dialog(*_):
        await pick_files_dialog.pick_files_async(allow_multiple=True)

    await page.add_async(
        ft.Row(
            [
                ft.ElevatedButton(
                    "Pick files",
                    icon=ft.icons.UPLOAD_FILE,
                    on_click=show_dialog,
                ),
                selected_files,
            ]
        )
    )
