indexOf method

int indexOf(
  1. int value, [
  2. int start = 0,
  3. int? end
])

Returns the first index of value in [start, end), or -1.

Implementation

int indexOf(int value, [int start = 0, int? end]) {
  final e = end ?? _length;
  RangeError.checkValidRange(start, e, _length);
  final i = asUint8List().indexOf(value, start);
  return i >= 0 && i < e ? i : -1;
}
