# convert method

String convert (List<int> bytes, [ int start = 0, int end ])

Converts the `bytes` (a list of unsigned 7- or 8-bit integers) to the corresponding string.

If `start` and `end` are provided, only the sub-list of bytes from `start` to `end` (`end` not inclusive) is used as input to the conversion.

## Implementation

    String convert(List<int> bytes, [int start = 0, int end]) {
      int byteCount = bytes.length;
      RangeError.checkValidRange(start, end, byteCount);
      if (end == null) end = byteCount;

      for (int i = start; i < end; i++) {
        int byte = bytes[i];
        if ((byte & ~_subsetMask) != 0) {
          if (!_allowInvalid) {
            throw new FormatException("Invalid value in input: $byte");
          }
          return _convertInvalid(bytes, start, end);
        }
      }
      return new String.fromCharCodes(bytes, start, end);
    }
