Easily manage connecting to a WebSocket server, subscribing to messages, handling reconnections etc all at once with djangoflow_websocket

djangoflow_websocket #

The project offers a set of classes and utilities to simplify WebSocket communication in Flutter applications. The core component is the DjangoflowWebsocketCubit, which manages the WebSocket connection, emits DjangoflowWebsocketState objects to represent the WebSocket state, and provides methods to connect and disconnect from the server. It handles automatic reconnection in case of connection failures.

The DjangoflowWebsocketBlocListener class, extending BlocListener, simplifies listening to new WebSocket messages by executing a callback whenever a new message is received.

Description #

The project aims to provide a seamless integration of WebSocket functionality in a Flutter application using the DjangoflowWebsocketCubit class. It allows re/connecting to a WebSocket server, subscribing to messages, handling reconnections, and managing the WebSocket state. Under the hood it extends DjangoflowWebsocketCubitBase and websocket_channel.

Installation #

To install the project, follow these steps:

  • Add the project dependency to your pubspec.yaml file:
djangoflow_websocket: ^x.x.x
  • Run flutter pub get to fetch the dependency.

Usage #

To use the project in your Flutter application, follow these steps:

  • Import the necessary classes:
import 'package:flutter/widgets.dart';
import 'package:flutter_bloc/flutter_bloc.dart';
import 'package:djangoflow_websocket/blocs/djangoflow_websocket_cubit/djangoflow_websocket_cubit.dart';
  • Create an instance of the DjangoflowWebsocketCubit:

    final websocketCubit = DjangoflowWebsocketCubit();
  • Wrap your application with a BlocProvider to make the websocketCubit available throughout the app:

    value: websocketCubit,
    child: MyApp(),
    • Use BlocBuilder to display the connection status:
    BlocBuilder<DjangoflowWebsocketCubit, DjangoflowWebsocketState>(
    builder: (context, state) {
          return Text(state.connectionStateMessage);
    • Use DjangoflowWebsocketBlocListener to listen to new WebSocket messages:
    bloc: websocketCubit,
    listener: (context, state) {
      if (state.message != null) {
          // Handle new message received
          print('New message: ${state.message}');
      child: Container(),
    • Connect to the WebSocket server:
    final uri = Uri.parse('wss://');
    • Disconnect from the WebSocket server when no longer needed:

Note DjangoflowWebsocketCubitBase can be extended to create more customizable Cubits to manage websocket connections.

DjangoflowWebsocketCubit #

connectToUri(Uri uri)

Connects to a WebSocket server at the specified uri. Emits connection state messages using the DjangoflowWebsocketState class.

disconnect({int? closeCode, String? closeReason})

Disconnects from the WebSocket server. Closes the channel sink and cancels the subscription.

sendMessage #

Send message to the WebSocket server.


An immutable class that represents the state of the WebSocket connection. Includes properties like connectionStateMessage and message.


A widget that listens to state changes from the DjangoflowWebsocketCubit and executes a callback when a new message is received.
