stringMatch abstract method Null safety

String? stringMatch(
  1. String input

Finds the string of the first match of this regular expression in input.

Searches for a match for this regular expression in input, just like firstMatch, but returns only the matched substring if a match is found, not a RegExpMatch.

var string = 'Dash is a bird';
var regExp = RegExp(r'(humming)?bird');
var match = regExp.stringMatch(string); // Match

regExp = RegExp(r'dog');
match = regExp.stringMatch(string); // No match


String? stringMatch(String input);
