Custom Map Markers

Not only “Everything is a widget” also “Everywhere is a widget“.
custom_map_marker is a package that turns runtime widgets into map marker icons.


this package providers the following features:

  • Ability to create runtime map markers using flutter widgets.
  • Capture Images of any list of widgets.

Getting started

First, add custom_map_markers as a dependency in your pubspec.yaml file.

  custom_map_markers: ^0.0.1


  1. Wrap your GoogleMaps widget with CustomGoogleMapMarkerBuilder.
  2. Define each marker and its custom widget in customMarkers
  3. Once custom markers are ready they will be passed as Set<Marer> in builder function.

final locations = const [  
  LatLng(37.42796133580664, -122.085749655962),  
  LatLng(37.41796133580664, -122.085749655962),  

  customMarkers: [  
        marker: Marker(  markerId: const MarkerId('id-1'), position: locations[0]),  
		child: _customMarker('A',,  
        marker: Marker(  markerId: const MarkerId('id-2'), position: locations[1]),  
		child: _customMarker('B',,    
  builder: (BuildContext context, Set<Marker>? markers) {  
    if (markers == null) {  
      return const Center(child: CircularProgressIndicator());  
    return GoogleMap(  
      initialCameraPosition: const CameraPosition(  
        target: LatLng(37.42796133580664, -122.085749655962),  
  zoom: 14.4746,  
  markers: markers,  
  onMapCreated: (GoogleMapController controller) { },  

Not a google map user?

if you are not willing to use google maps you can use
CustomMapMarkerBuilder that takes List<widgets> instead of List<MarkerData> and returns List<Uint8List> instead of Set<Marker> so you are free to use captured png images as you need.


  1. Make sure your marker widget has boundaries.
  2. This package capture a png image of widget markers once they render, if your widget would take more time to render like you can use screenshotDelay parameter to daley the capture process making sure that your widget is rendered properly before capturing it.
  3. to run project example you have to add a valid google maps key to android/ios directories.
