folder picker besides file picker

Question

I've been looking for a solution to select a folder in native mode. But so far I've not been successful.

There was a good discussion on file&folder pickers, but that only resulted in a file picker:
#283

I've tried below, and you can drag in a folder into the ui.upload d&d box. But it trows an error when uploaded.
And the create_file_dialog does exactly what it says on the tin: select a file.

async def choose_file():
    files = await app.native.main_window.create_file_dialog(allow_multiple=True)
    for file in files:
        ui.notify(file)


class AppUI:
    def __init__(self):
        app.native.settings['ALLOW_DOWNLOADS'] = True

        self.left_drawer = self.fill_left_drawer()
        self.right_drawer = self.fill_right_drawer()
        self.header = self.fill_header()
        self.footer = self.fill_footer()

        ui.label('CONTENT')
        ui.button('choose file', on_click=choose_file)
        x = ui.upload(on_upload=lambda e: ui.notify(f'Uploaded {e.name}'), auto_upload=True).classes('max-w-full')

TL;DR: Would it not be nice to be able to select a folder for native apps? this might be useful for outputs, or for example to process all images in a given folder

Hi @da-i,

You can do that by passing a dialog_type to create_file_dialog:

folders = await app.native.main_window.create_file_dialog(allow_multiple=True, dialog_type=webview.FOLDER_DIALOG)
