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.

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.
