Can we retrieve data from Firebase?

If you open your app from Firebase dashboard, you can add data manually by clicking on the + sign .

Firebase data is retrieved by either a one time call to GetValueAsync() or attaching to an event on a FirebaseDatabase reference . The event listener is called once for the initial state of the data and again anytime the data changes.

Go to the Firebase Console, select your project and click on the Database tab. Scroll down and you will find a Realtime Database section. Click on Create database, select the Start in test mode option and then click Enable.
