replaceAfter method

String replaceAfter(
  1. String delimiter,
  2. String replacement, [
  3. String defaultValue = ''
])

Replace part of string after the first occurrence of given delimiter with the replacement string. If the string does not contain the delimiter, returns defaultValue which defaults to the original string.

Implementation

String replaceAfter(String delimiter, String replacement, [String defaultValue = '']) {
  final index = indexOf(delimiter);
  return (index == -1)
      ? defaultValue.isEmpty
          ? this
          : defaultValue
      : replaceRange(index + 1, length, replacement);
}
