1 Convert List of Strings to List of Integers

In this example,

We have a list of strings named stringList.
We use the map() function to iterate over each string in the list and convert it to an integer using the int.parse() function.
The result is a list of integers.

Dart Program

void main() {
  List<String> stringList = ["1", "2", "3", "4", "5"];
  List<int> intList = stringList.map((s) => int.parse(s)).toList();
  print("List of integers: $intList");
}

Output

List of integers: [1, 2, 3, 4, 5]
