mapController.addMarker( MarkerOptions( position: LatLng(37.4219999, -122.0862462), ), );
I've seen this code snippet in a blog post, and I'm trying to add markers to Google Maps.
The method 'addMarker' isn't defined for the class 'GoogleMapController'.
I think the library has changed and I want to know what's the new way doing this, I've looked up in the controller.dart and api reference but couldn't figure it out.
I would be happy to see some tutorials and blog posts about it, don't hesitate to share.
In Syncfusion Flutter Maps, you can add a marker in the current location easily. Step 1: Add location and syncfusion_flutter_maps packages to your dependencies in pubspec. yaml file. Step 2: Import the below libraries in your dart file.
Yes, The google maps API has changed and the Marker API is widget based and not based in controller anymore.
By CHANGELOG.md
"Breaking change. Changed the Marker API to be widget based, it was controller based. Also changed the example app to account for the same."
I copy some pieces of code from github app example that I think is important to you
Map<MarkerId, Marker> markers = <MarkerId, Marker>{}; // CLASS MEMBER, MAP OF MARKS void _add() { var markerIdVal = MyWayToGenerateId(); final MarkerId markerId = MarkerId(markerIdVal); // creating a new MARKER final Marker marker = Marker( markerId: markerId, position: LatLng( center.latitude + sin(_markerIdCounter * pi / 6.0) / 20.0, center.longitude + cos(_markerIdCounter * pi / 6.0) / 20.0, ), infoWindow: InfoWindow(title: markerIdVal, snippet: '*'), onTap: () { _onMarkerTapped(markerId); }, ); setState(() { // adding a new marker to map markers[markerId] = marker; }); } GoogleMap( onMapCreated: _onMapCreated, initialCameraPosition: const CameraPosition( target: LatLng(-33.852, 151.211), zoom: 11.0, ), // TODO(iskakaushik): Remove this when collection literals makes it to stable. // https://github.com/flutter/flutter/issues/28312 // ignore: prefer_collection_literals markers: Set<Marker>.of(markers.values), // YOUR MARKS IN MAP )
I advise you take a look in example app here. There is updated to new API.
