# lastIndexOf method

int lastIndexOf(

1. int value, [
2. int? start

])

Returns the index of the last occurrence of the specified byte.

`value` the byte to search for `start` the starting index from the end (optional) Returns -1 if not found

## Implementation

    int lastIndexOf(int value, [int? start]) {
      int startIndex = start ?? _bytes.length - 1;
      for (int i = startIndex; i >= 0; i--) {
        if (_bytes[i] == value) return i;
      }
      return -1;
    }
