Package Overview

Package selection guidance compiled from public package information, community data, and project usage.

Livestream is a lightweight Flutter package designed to simplify communication between different parts of an application. It provides a straightforward way to broadcast and listen to events, making it ideal for state management and inter-module communication without the complexity of larger frameworks. The package is built around a simple publish-subscribe pattern, enabling efficient data flow across widgets, services, or screens. With minimal setup and no external dependencies, Livestream enhances modularity and responsiveness in Flutter apps.

Subscribe to Stream / Add Observer

LiveStream event will be dispatched when data is changed. See below code to add observer / subscriber.

    liveStream.on("chat-message", (message) {
      print("Message Received: $message");
    });

Whenever data is emitted to chat-message channel/stream above block will be executed.

Emitting Events or Broadcasting

The main idea behind LiveStream is that you can send and receive any events you want, with any data you want. Any objects that can be encoded as JSON will do, and binary data is supported too. See code below.

  void send() {
      String message = "Hi there!";
      liveStream.emit("chat-message", message);
  }
