Is it possible to modify the camera zoom point in Flutter?

edit

Yes, it is possible to modify the camera zoom point in Flutter using the CameraPosition class's zoom parameter. The zoom parameter ranges from 0.0 to 21.0, where 0.0 represents the furthest zoom level (i.e., the entire world map), and 21.0 represents the closest zoom level (i.e., street-level).

To modify the camera zoom point, you can create a new CameraPosition object with the desired zoom level and set it as the CameraPosition for your GoogleMap widget:

GoogleMap(
  initialCameraPosition: CameraPosition(
    target: LatLng(37.7749, -122.4194),
    zoom: 15.0, // Set initial zoom level here
  ),
  onMapCreated: (GoogleMapController controller) {
    // ...
  },
)

Then, you can modify the zoom level dynamically by creating a new CameraPosition object with the updated zoom level and calling the animateCamera method on your GoogleMapController:

GoogleMapController controller; // This should be set in `onMapCreated`

void _updateZoom(double newZoom) {
  CameraPosition newCameraPosition = CameraPosition(
    target: controller.cameraPosition.target,
    zoom: newZoom,
  );

  controller.animateCamera(CameraUpdate.newCameraPosition(newCameraPosition));
}
