Displaying array with index in Dart Flutter

Padding(
  padding: const EdgeInsets.all(8.0),
  child: Column(
           crossAxisAlignment: CrossAxisAlignment.start,
           mainAxisAlignment: MainAxisAlignment.center,
           children: <Widget>[
             for (var i = 0;i < snapshot.data[0]["meanings"][index]["definitions"].length;i++)
               for (var item in snapshot.data[0]["meanings"][index]["definitions"])
                 Text(
                   (i + 1).toString() + ". " + item["definition"],
                   textAlign: TextAlign.left,
                 )
           ],
         ),
       )

This is the result the code gives: Code Result

enter image description here I would like something like:

  1. A party...
  2. A hairdo
  3. Something that.... ...

List should end at 7 which is the length of the array

In order to get rid of unnecessary repetition you just simply have to get rid of your nested for loop, which is totally redundant here. Access your item with loop index - snapshot.data[0]["meanings"][index]["definitions"][i]["definition"]

Padding(
  padding: const EdgeInsets.all(8.0),
  child: Column(
           crossAxisAlignment: CrossAxisAlignment.start,
           mainAxisAlignment: MainAxisAlignment.center,
           children: <Widget>[
             for (var i = 0;i < snapshot.data[0]["meanings"][index]["definitions"].length;i++)
                 Text(
                   (i + 1).toString() + ". " + snapshot.data[0]["meanings"][index]["definitions"][i]["definition"],
                   textAlign: TextAlign.left,
                 )
           ],
         ),
       )
