A dart client for GraphQL subscriptions via Absinthe sockets
Use the package:
# pubspec.yaml
# ...
absinthe_socket: ^0.0.3
# ...Create a socket, connect it, add a subscription:
_socket = AbsintheSocket("ws://10.0.2.2:4000/socket/websocket");
Observer _categoryObserver = Observer(
onAbort: _onAbort,
onCancel: _onCancel,
onError: _onError,
onResult: _onResult,
onStart: _onStart);
Notifier notifier = _socket.send(GqlRequest(
operation:
"subscription CategoryAdded { categoryAdded { id, title } }"));
notifier.observe(_categoryObserver);
// I also track notifiers to cancel them when my flutter widget is disposed of
_notifiers.add(notifier);
// Then when the widget is disposed, I cancel the notifiers:
_notifiers.forEach((Notifier notifier) => _socket.cancel(notifier))
// And you can disconnect the socket:
_socket.disconnect();This is a shameless bad rip-off of part of the API of @absinthe/socket.
