In this tutorial we are going to elaborate on what are the common ways to add support for persistent storage in Flutter apps. More precisely, we are going to create a real app, and showcase in details how to persist data to disk in Flutter apps.

Most of the mobile applications today store some data that will be used again and again every time the application is launched. On mobile devices, the application can run in the background or exit at any time. While exiting, the app can be in any state. Now, it is necessary for the application code to take care of this without the users having to concern themselves on whether that data of a particular state has been appropriately stored for later access.
