# Flutter Community Chat

Flutter Community Chat is a package which gives the possibility to add a (personal or group) chat to your Flutter-application. Default this package adds support for a Firebase back-end. You can add your custom back-end (like a Websocket-API) by extending the `CommunityChatInterface` interface from the `flutter_community_chat_interface` package.
