About Flutter Firebase Chat

This is a fully-functional chat application template based on Flutter and FireBase. The project helps you to launch your own messenger application in a few clicks and publish it to the stores.

Inside the Package

  • Database architecture built entirely on Firebase;
  • The design is made according to the rules of Material Design;
  • Cross-platform code implemented on Flutter.

Main Functions AChat – Flutter Firebase Chat and Messenger Premium Template

We have researched hundreds of repositories on github on the topic of instant messengers and chats, (at the time of publication of 2000+ repositories). Each of the repositories offers fairly limited options for creating chats on Flutter. For example, only sending messages from one user to another or the ability to send pictures. But almost nobody bothered with the functionality of deleting messages. There are hundreds of such micro-chips necessary in a good messenger today.


We have implemented most of the necessary features in Flutter Firebase chat. That is without what the chat application template is essentially bonfire. The list of features of our messenger template in version 1.0.0:

Used Firebase modules

  1. Cloud Functions;
  2. Cloud Messaging;
  3. Firebase Authentication;
  4. Cloud Firestore;
  5. Cloud Storage.
The architecture of the application is written in such a way as to spend less quota on Firebase. Almost all dynamically transmitted data is stored in local preferences. This saves Firebase traffic. The architecture also allows the application to work several times faster, since it does not wait for a response from Firebase, and it takes most of the necessary data from the local storage. This plays a huge role if you have poor internet. If you are going to make a small application, then the free Firebase tariff may be enough for you.
