show method

Future<UniqueKey> show({ String title = 'Error', String? desc, DialogType type = DialogType.error, })

Displays a custom dialog.

The dialog is shown as a SnackBar at the bottom of the screen.

Optionally takes a title, desc (description), and type of dialog. The type influences the appearance of the dialog.

Returns a Future that resolves with a UniqueKey identifying the displayed dialog. This key can be used to hide the specific dialog later.

If an error occurs during the process (e.g., ScaffoldMessengerState is null), a CustomException is thrown.
