Convert List of String to List of int Dart

Question

How to convert a list from one type to another without a for loop?

List <String> lstring = <String>["1", "2"];
List <int> lint = lstring.map(int.parse);

I get the error:

type 'MappedListIterable<String, int>' is not a subtype of type 'List<int>'

Answer 1

You need to add a toList() to the end of the second line.

List <String> lstring = <String>["1", "2"];
List <int> lint = lstring.map(int.parse).toList();

This will do it.
