# isLength method

bool isLength(

1. int min, [
2. int? max

])

Check if the string's length falls in a range If no max is given then any length above min is ok.

Note: this function takes into account surrogate pairs.

## Implementation

    bool isLength(int min, [int? max]) {
      var str = this;

      final surrogatePairs = RegexUtils.surrogatePairs.allMatches(str).toList();
      int len = str.length - surrogatePairs.length;
      return len >= min && (max == null || len <= max);
    }
