IndicatorService class

A service class to display and manage a custom indicator using a SnackBar.

This service allows showing a persistent indicator, such as a loading spinner or an animation with a logo, typically used to indicate ongoing processes like network requests. It leverages a GlobalKey<ScaffoldMessengerState> to display the indicator as a SnackBar at the bottom of the screen.

An indicator widget or a logo image must be provided during initialization. If both are provided, the custom indicatorWidget takes precedence.
