I am doing here student results app, I converted csv to json data then I sent it to database. now I want to to get back and get all map data without identifying subjects or any other key.
if any one has more educated then me about this topic help me to do it.
many thanks.

Instead of for loop, you can use map method on your results[index]'s entries, it will return you MapEntry of your items inside results[index], then you can use its key and value to generate your listview's items. Try this:

Column(
    children: map.entries.map((e) => Align(
            alignment: Alignment.centerLeft,
            child: Text(
              e.key.toString() + ' : ' + e.value.toString(),
            ),
          ),).toList()
  ),
