Dart - Encode and decode base64 string

Question

How to native convert string -> base64 and base64 -> string

I'm find only this bytes to base64string

would like this:

String Base64String.encode();
String Base64String.decode();

or ported from another language is easier?

Answer 1

As of 0.9.2 of the crypto package

CryptoUtils is deprecated. Use the Base64 APIs in dart:convert and the hex APIs in the convert package instead.

import 'dart:convert' show utf8, base64;

main() {
  final str = 'https://dartpad.dartlang.org/';

  final encoded = base64.encode(UTF8.encode(str));
  print('base64: $encoded');

  final str2 = utf8.decode(base64.decode(encoded));
  print(str2);
  print(str == str2);
}

Try it in DartPad
