add method
Adds raw bytes to the output sink.
The data is sent almost immediately, but if you want to be sure,
there is this.allSent
that provides future which completes when
all added data are sent.
You should use some encoding to send string, for example ascii.encode('Hello!')
or utf8.encode('Cześć!)
.
Might throw StateError("Not connected!")
if not connected.
Implementation
@override
void add(Uint8List data) {
if (!isConnected) {
throw StateError("Not connected!");
}
_chainedFutures = _chainedFutures.then((_) async {
if (!isConnected) {
throw StateError("Not connected!");
}
await _instance.write(_id, data);
}).catchError((e) {
if (kDebugMode) print(e);
close();
});
}
