How to get bytes of a String in Dart?

Question

How can I read the bytes of a String in dart? in Java it is possible through the String method getBytes().

See example

Answer 1

import 'dart:convert';

String foo = 'Hello world';
List<int> bytes = utf8.encode(foo);
print(bytes);

Output: [72, 101, 108, 108, 111, 32, 119, 111, 114, 108, 100]

Also, if you want to convert back:

String bar = utf8.decode(bytes);
