This factory method attempts to fallback to other available ui_types on ImportError. For example, if `ui_type` is `curses`, but `curses` cannot be imported properly, e.g., on Windows, will fallback to `readline`. Args: ui_type: (`str`) requested UI type. Currently supported: (curses | readline) on_ui_exit: (`Callable`) the callback to be called when the UI exits. available_ui_types: (`None` or `list` of `str`) Manually-set available ui_types. config: An instance of `cli_config.CLIConfig()` carrying user-facing configurations. Returns: A `base_ui.BaseUI` subtype object. Raises: ValueError: on invalid ui_type or on exhausting or fallback ui_types.
