Overview
The widget_to_marker package enables developers to convert any Flutter widget into a BitmapDescriptor, allowing custom-designed widgets to be used as icons on Google Maps markers via the google_maps_flutter plugin. This is particularly useful for creating visually rich, dynamic markers that go beyond standard icons. The package supports Android, iOS, and Web platforms, ensuring cross-platform consistency. It simplifies the process of rendering complex UI elements like avatars, badges, or custom shapes directly on maps.
