How to make sum of double value in a string in flutter?

One way you can do is like this.

  String str = "(2.0, 1.0, 1.0, 3.0, 5.0)";
  str = str.replaceAll("(","");
  str = str.replaceAll(")","");
  List<String> strDoubles = str.split(", ");
  
  double sum = 0;
  strDoubles.forEach((String item){
    sum = sum + double.parse(item);
  });
  print(sum);       //<-- prints 12
