setUint16 method
Sets the two bytes starting at the specified byteOffset in this object
to the unsigned binary representation of the specified value,
which must fit in two bytes.
In other words, value must be between
0 and 216 - 1, inclusive.
Throws RangeError if byteOffset is negative, or
byteOffset + 2 is greater than the length of this object.
Implementation
void setUint16(int byteOffset, int value, [Endian endian = Endian.big]);
