Appwrite is a secure, open source back-end server, which you can easily setup using only docker. It can used as a back-end service for our Web and Mobile applications including Flutter. It is great for Flutter developers to have Appwrite in their toolbox, as this will give them alternative to Firebase, or building own service in back-end. This is unique opportunity for Flutter developers, as they can focus on their application rather than on setting up a remote database and API and managing that application on their own. So, in this ongoing tutorial series, we will learn to setup Appwrite and use it as a back-end for our flutter application.
