add method
Adds byte data
to the target consumer, ignoring encoding.
The encoding does not apply to this method, and the data
list is passed
directly to the target consumer as a stream event.
This method must not be called when a stream is currently being added using addStream.
This operation is non-blocking. See flush or done for how to get any errors generated by this call.
The data list should not be modified after it has been passed to add
because it is not defined whether the target consumer will receive the
list in the original or modified state.
Individual values in data
which are not in the range 0 .. 255 will be
truncated to their low eight bits, as if by int.toUnsigned, before being
used.
Implementation
@override
void add(List<int> data) {
_addItems(data);
_httpClientRequest.add(data);
}
