Many companies build Flutter chat apps without firebase, which are less functional and sometimes lack compatibility. But with the firebase module, you develop a highly scalable and performing app for the client. So, here are quick steps:

1. Firebase Authentication

The very initial and vital step is to create an authentic sign-up to protect the chat app from any disguise. Now comes the understanding part. If the developer uses the Google Sign-up concept, a developer can use terminal/CMD or VS code.

These will work as the systematic code editor and offer great support for development functions like debugging task running and version control. Now create a sign-in widget in the Sign-in. Dart, and here you will utilize the framework, appBar, body, and floating buttons.

2. Installing Widgets For Functionality

Concerning the Flutter chat room, it is essential to properly coordinate among the plugins to run it flawlessly. By arranging the plugins properly, the developer can create and assemble a main Firebase chat application.

To install any plugin on the app, you need to follow the guidelines of incorporating “Firebaseauth, google sign in, cloud firestore, firebase storage, etc., to the app with firebase.

3. Layout of the Screen

The next task is to prepare a layout of the app screen. In a chat application, different screens are available. It holds an enlistment screen, login screen, setting screen, landing page, and chat screen.

This load of the screen is built by creating several arrangements of codes. It is the only reason why the developer has to follow the guidelines properly. There are four prominent types of screen layout, i.e., Login screen layout, Main screen layout, Setting screen layout, Chat screen layout.

4. Connection with Flutter & Firebase

Another essential part of the flutter chat app development is to connect it with firebase. A developer has to sign up with a Google account or Sign in to the firebase to do so. Now, you have to create a project and then construct Project Overview.

In this segment, you have to add your Package Name. Download google-services.json and move the downloaded file in the Android app module root directory. Now add the google-services dependencies in the Project-level build. Gradle and you are good to go.

So these were the four significant steps to build a chat app with flutter. Now we will look at the benefits of developing a chat app in a flutter with firebase.
