flutter_firebase_chat_sdk 0.0.1

A new Flutter package.

flutter_firebase_chat_sdk

A package that used the power of firebase to create a chat SDK.

Motivation behind this project was to create an all in one sdk that would make it easier for developers to create a chat app. Using this SDK developers can focus on the basic functionality of their app rather then worrying about setting up and developing a chat server.

The project is still in development phase but you are welcome to use it in your app and contribute to the project if you needed some more features or if you would like to improve something.

Demo

Getting Started

• Using this link setup Firebase in your app
• Setup Authentication, Cloud Firestore, Realtime Database and Storage on your Firebase project
• Add await FlutterFirebaseChatSDK.initializeApp() to your main() method

void main() async {
  WidgetsFlutterBinding.ensureInitialized();
  await FlutterFirebaseChatSDK.initializeApp();
  runApp(MyApp());
}

• Wrap your app with FlutterFirebaseObservableApp widget so that the SDK could monitor the status of the app which is needed to update the online status of the user. So for example your main app widget could be:

class MyApp extends StatelessWidget {
  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        primarySwatch: Colors.blue,
        visualDensity: VisualDensity.adaptivePlatformDensity,
      ),
      home: FlutterFirebaseObservableApp(
        child: FlutterFirebaseChatSDK.instance.isUserLoggedIn ? Home() : Login(),
      ),
    );
  }
}

• It is also a good idea from security purposes to perform some operations from the server and not give access to client for them. One of the example for this is the addFriend function which calls a firebase functions and invokes the firebase admin SDK to add a new friend and create a chat group with current user and the given friend id.

• Use this link to setup firebase CLI on your system and firebase functions in your project and then add code from lib/firebase/firebase-functions.js to the index.js file of your firebase functions project and run npm install uuidv4 to install uuidv4 dependency.

• The project also uses firebase collection group so add the following rules to your CloudFirestore rules

match /{path=**}/Channels/{channelId} {
    	allow read, writw: if request.auth != null
    }

• It might be a good idea to add strict rules to your project including your Cloud Firestore, Realtime Database and Storage to prevent anykinds of attack on your Firebase project and causing you finantial loss. Realtime database rules, Cloud firestore rules, Storage rules these links could be a good starting point to setting up security rules for protecting your project from any kind of attacks.
