Dart parse date with +0000 – Twitter API

I am using the Twitter api for getting tweets in a Flutte App.
The api returns a formatted date like this:

Wed Jun 12 00:08:35 +0000 2019

  DateTime formatTwitterDate() {
    final format = DateFormat('EEE MMM dd hh:mm:ss +0000 yyyy'); //todo failed to resolve +0000
    return format.parse(this);
  }

This is the only formatter I got working. How can I support +0000?

    extension StringToDateTime on String {
  DateTime formatTwitterDate() {
    final newDateString = '${replaceAll('+0000 ', '')} UTC';
    final format = DateFormat('EEE MMM dd hh:mm:ss yyyy Z');
    return format.parse(newDateString);
  }
}

    Porting this answer to dart

      var s = "Fri Apr 09 12:53:54 +0000 2010";
  print(s);

  final newString =
      s.replaceAllMapped(RegExp(r'w+ (w+) (d+) ([d:]+) +0000 (d+)'), (m) {
    return "${m[1]} ${m[2]} ${m[4]} ${m[3]} UTC";
  });
  print(newString);
