# insert method

void insert(

1. int index,
2. int byte

)

Inserts a byte at the specified index.

Example:

    final bytes = Byte.fromList([1, 3, 4]);
    bytes.insert(1, 2);
    print(bytes.toList());  // [1, 2, 3, 4]

Throws InvalidArgumentException if value is outside byte range. Throws RangeError if index is invalid.

## Implementation

    void insert(int index, int byte) {
      _bytes.insert(index, _validateByteRange(byte));
    }
