google_maps_controller
Stateful map controller for Google Maps google_maps_flutter . Manage Markers, Circles, Polylines, and Polygons.
Inspired by map_controller for flutter_map .
Getting Started
Follow same config steps as decirbed in google_maps_flutter
getting-started .
Usage
Use GoogleMaps widget instead of GoogleMap to use auto set-up widget.
Use GoogleMapsController for all the actions.
Check example dir for more details.
var controller = GoogleMapsController ();
GoogleMaps (
controller: controller,
)
You can also provide controller through provider / InheritedWidget / BLoC or any other state management.
