You can use toString() metohd.

 String data =  list.toString();

please try this code

List<int> list= [1, 2, 3];String data  = list.toString().replaceAll('[', "'[").replaceAll(']',"]'");print(data);

you can try it on the dart pad to know the solution

Another way. Independent of the built-in 'toString()'.

void main() {
  final list = [1, 2, 3];
  final data = '[${list.join(', ')}]';
  print(data);
}
