Counter Service for WebSocket communication

Counter Service #

Counter Service is a Flutter package that provides a WebSocket-based counter functionality. It allows you to connect to a WebSocket server, increment or decrement a counter, and receive real-time updates.

Features #

  • WebSocket connection management
  • Real-time counter updates
  • Increment and decrement counter actions
  • Singleton pattern for easy access across your app
  • Error handling and connection status tracking

Getting started #

To use this package, add counter_service as a dependency in your pubspec.yaml file:

dependencies:
  counter_service: ^0.0.1

Then, run flutter pub get to install the package.

Usage #

Here's a quick example of how to use the Counter Service:

import 'package:counter_service/counter_service.dart';

void main() async {
  final counterService = CounterService();
  
  // Connect to the WebSocket server
  await counterService.connect('wss://your-websocket-server.com');
  
  // Listen for counter updates
  counterService.counterStream.listen((value) {
    print('Counter value: $value');
  });
  
  // Increment the counter
  await counterService.incrementCounter();
  
  // Decrement the counter
  await counterService.decrementCounter();
  
  // Get the current counter value
  print('Current counter value: ${counterService.counterValue}');
  
  // Disconnect when done
  counterService.disconnect();
}

Additional information #

Dependencies #

This package depends on:

  • web_socket_channel: 2.4.5 for WebSocket communication

Error Handling #

The Counter Service includes basic error handling and logging. You can extend the _onError method in the CounterService class to implement custom error handling or user notifications.

Reconnection #

The current implementation does not automatically reconnect on disconnection. You can implement reconnection logic in the _onDisconnected method if needed.
