    title: title,
    description: description,
  );
}

Example using bottom sheet #

  openMapsSheet(context) async {
    try {
      final title = "Shanghai Tower";
      final description = "Asia's tallest building";
      final coords = Coords(31.233568, 121.505504);
      final availableMaps = await MapLauncher.installedMaps;

      showModalBottomSheet(
        context: context,
        builder: (BuildContext context) {
          return SafeArea(
            child: SingleChildScrollView(

                    for (var map in availableMaps)
                      ListTile(
                        onTap: () => map.showMarker(
                          coords: coords,
                          title: title,
                          description: description,

                        title: Text(map.mapName),
                        leading: Image(
                          image: map.icon,
                          height: 30.0,
                          width: 30.0,
                        ),
