Have you ever wanted to send a message to another part of the app but don't want to create a direct connection? This package allows you to send and listen topic anywhere. Can connect to any topic in anywhere and get data without direct direction.
- Emit topic and send data.
- Listen topic and recieve data.
- Close topic listen.
- ReOpen connection when is already closed.
- Open a command line and cd to your projects root folder
- In your pubspec, add an entry for fkafka to your dependencies (example below)
- flutter pub get
There are 2 options. Directly from git, or from pub.dartlang.org
pub.dartlang.org: (you can use 'any' instead of a version if you just want the latest always)
dependencies:
fkafka: 0.1.0
import 'package:fkafka/fkafka.dart';
final kafka = Fkafka();
kafka.emit(
topic,
TopicData(
action: FkafkaAction.created // created, edited, deleted, changed,
data: {
'foo': 'bar'
},
),
);
Is necessary create a new instance to listen topics, try not use the same instance in more topics because is you try to close connection it will close in all topics listen in the same instance.
final kafka = Fkafka();
kafka.on(
TulTopics.cart,
(TopicData topic) {
print(topic);
},
);
This method allows you to close topic listener.
kafka.close();
