This snippet shows how to set toggledItemColor in SfMaps.

late List<DataModel> _data;
late MapShapeSource _mapSource;

 @override
 void initState() {
   super.initState();

   _data = <DataModel>[
     DataModel('India', 280, "Low"),
     DataModel('United States of America', 190, "High"),
     DataModel('Pakistan', 37, "Low"),
   ];

   _mapSource = MapShapeSource.asset(
     "assets/world_map.json",
     shapeDataField: "name",
     dataCount: _data.length,
     primaryValueMapper: (int index) {
       return _data[index].country;
     },
     shapeColorValueMapper: (int index) {
       return _data[index].storage;
     },
     shapeColorMappers: [
       MapColorMapper(value: "Low", color: Colors.red),
       MapColorMapper(value: "High", color: Colors.green)
     ],
   );
 }

 @override
 Widget build(BuildContext context) {
   return Scaffold(
     appBar: AppBar(
       title: Text('Default legend'),
     ),
     body: Center(
       child: SfMaps(
         layers: [
           MapShapeLayer(
             source: _mapSource,
             legend: MapLegend(
               MapElement.shape,
               enableToggleInteraction: true,
               toggledItemColor: Colors.blueGrey
             ),
           )
         ],
       ),
     ),
   );
 }

class DataModel {
  const DataModel(this.country, this.count, this.storage);

  final String country;
  final double count;
  final String storage;
}
