Implemented types

Constructors

WebSocketOpcUaByteTransport({required Uri endpoint, List<String> subprotocols = const ['opcua+cp'], Duration? connectTimeout})

Properties

connectTimeout → Duration?

final
hashCode → int
The hash code for this object.
no setterinherited
incoming → Stream<Uint8List>

no setter
runtimeType → Type
