A package which allow developers to develop the shiSock client for the there flutter android app. Using flutter-shiSock developers can develop a chat application very easily. It can also be used in app in which we need real time data flow.

Features

It is easy to settup.

It can be used for different kinds of applications like chat, weather forecast, etc.

shiSock Engine has very low letency while handling millions of concurrent users.

Getting started

Run these command according to your environment.

With Dart:

$ dart pub add flutter_shisock

With Flutter:

Run this command in temrinal from the root of your project

$ flutter pub add flutter_shiSock

OR:

You can also directly add this line into you project's pubspec.yml file in dependencies section

    dependencies:
        flutter_shiSock: ^1.0.0

Usage

A example minimilistic chat application.

In this example, in case you shiSock Engine and server is running in localhost then localhost for android emulator would be 10.0.2.2. Our in case shiSock Engine is running in cloud then you have to provide the public ip of device on which the Engine is running.

import 'package:flutter/material.dart';
import 'package:shisock_flutter/shisock_flutter.dart';

// main function or the starting point
void main() {
  runApp(MyApp());
}


// The main class for the flutter application and it is the root 
// of you application.
class MyApp extends StatelessWidget {

  // The declaration and initialisation of the shiSockClient object.
  ShiSockClient client = ShiSockClient();

  // If running on Android Emulator, 10.0.2.2 will the localhost
  String address = "10.0.2.2";
  int port = 8080;

  // shiSockListener object which will be used later in the application,
  // that's why it declared using late keyword.
  late ShiSockListener shiSock;

  // The construction of class. It is used to initialise the shiSock variable.
  MyApp({Key? key}) : super(key: key) {

    // Initialisation of shiSock variable using client' connect function.
    // connect function return a shiSockListener object.
    shiSock = client.connect(address, port);
  }

  // Root build function of the application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
      ),
      home: MyHomePage(shiSock: shiSock),
    );
  }
}

// A stateful widget class becouse there will the changes in the application UI
// on the fly.
class MyHomePage extends StatefulWidget {
  const MyHomePage({Key? key, required this.shiSock}) : super(key: key);
  final ShiSockListener shiSock;
  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

// A simple UI class.
class _MyHomePageState extends State<MyHomePage> {
  final myController = TextEditingController();
  List<Map<String, String>> msg = [];
  void listener() {
    widget.shiSock.listen("main", (data, sender) {
      setState(() {
        msg.add(data);
      });
    });
  }
