# group abstract method

String? group(

1. int group

)

The string matched by the given `group`.

If `group` is 0, returns the entire match of the pattern.

The result may be `null` if the pattern didn't assign a value to it as part of this match.

    final string = '[00:13.37] This is a chat message.';
    final regExp = RegExp(r'^\[\s*(\d+):(\d+)\.(\d+)\]\s*(.*)$');
    final match = regExp.firstMatch(string)!;
    final message = jsonEncode(match.group(0)!); // '[00:13.37] This is a chat message.'
    final hours = jsonEncode(match.group(1)!); // '00'
    final minutes = jsonEncode(match.group(2)!); // '13'
    final seconds = jsonEncode(match.group(3)!); // '37'
    final text = jsonEncode(match.group(4)!); // 'This is a chat message.'

## Implementation

    String? group(int group);
