how to get key from map in flutter at required position's key in flutter

Its not easy for me to explain what I want and thats why I have created this demo to make my point clear…

I have a data mymap which key is based on random number and value is bool

in my list tile of listview builder, I want sometime value and sometime key in it’s
title,subtitle,trailing,leading

class HomeScreen extends StatelessWidget {



  Map<String,dynamic> mymap={
    '${Random().nextInt(255)}':false,
    '${Random().nextInt(255)}':true,
    '${Random().nextInt(255)}':true,
    '${Random().nextInt(255)}':false,
   

  };

@override
  Widget build(BuildContext context) {
    return ListView.builder(
        itemCount: 1,
        itemBuilder: (context,index){

          return ListTile(
            title: Text(
                //firstkey + value
            ),
            subtitle: Text(
              //secondkey +value
            ),

            leading: Text(
              //thirdkey only
            ),
            trailing: Text(
              //fourthkey's value
            ),
          );

        });
  }
}

>Solution :

You can get keys like here:

List keys = myMap.keys.toList();

And get access to keys in list tile like here:

Text(keys[2].toString()), // get key from list index
