App functional features

• Third party login

Third party login would involve Google, Facebook and Apple login. We will also see how to login using phone number. The chatting feature of this is very seamless since we used SQFLITE to save the chatting history locally. First we save chat messages locally and send them to the other end in the background service.

So users feel like the app very fast sending messages. The same happens for sending images. We first save the image locally and then send to other user.

We also save user profile locally, so you don't have to confirm with Firebase or Laravel for login.

Next time a user logs in, user will feel like it's fast, since we read the data locally first. The same happens for chatting history. Chat history is read from local storage first.

Flutter framework

We used Flutter framework for building beautiful UI for both iOS and Android. In Flutter framework, we also cover a lot of Dart knowledge and how to use models and classes to work with view and controllers.

Firebase service

We used Firebase for sending users registration and phone number login. We used Firebase also for sending notification. Here in this tutorial you will more complex features of firebase like saving chat history, images, listening to document updates and uploading images.

Laravel framework

Laravel framework we used for building API for authentication. We used it also for saving basic information and communicating with Firebase for sending notification.

Agora SDK

We used Agora SDK for using video and audio call service. Agora provides very stable API for audio and video call.
