isContainsWord method

  1. @useResult
bool isContainsWord(
  1. String? find, {
  2. bool isCaseSensitive = false,
})

Returns true if this string contains find as a whole word.

When isCaseSensitive is false (default), comparison is case-insensitive.

Implementation

@useResult
bool isContainsWord(String? find, {bool isCaseSensitive = false}) {
  if (isEmpty || find == null || find.isEmpty) {
    return false;
  }

  final String escapedFind = find.replaceAllMapped(
    RegExp('[.*+?^\${}()|[\\]\\\\]'),
    (Match m) => '\\${m.group(0) ?? ''}',
  );
  final String pattern = '\\b$escapedFind\\b';
  final RegExp regex = RegExp(pattern, caseSensitive: isCaseSensitive);

  return regex.hasMatch(this);
}
