write method Null safety
Writes up to
count bytes of the buffer from
offset buffer offset to
the socket. The number of successfully written bytes is returned. This
function is non-blocking and will only write data if buffer space is
available in the socket.
The default value for
offset is 0, and the default value for
buffer.length - offset.
int write(List<int> buffer, [int offset = 0, int? count]);
