We then need to integrate Realtime Database in our Flutter app using the following steps:
- First, add the
firebase_databasepackage to thepubspec.yamlfile in the flutter dependancies section. - Next, add
databaseURLto themain.dartfile on the web Firebase initialization. The following code snippet show how this is achieved:apiKey: "AIzaSyAmOB_-8DIEIwJEOvrM2a8C6RE-KbvSDDc", projectId: "educative-9", storageBucket: "educative-9.appspot.com", //Here is the line databaseURL: "https://educative-9-default-rtdb.firebaseio.com", messagingSenderId: "14205101883", appId:"1:14205101883:web:7c0db5d88bc2dc0310791e",
Note: The keys we’ve mentioned (
apiKey,projectId,storageBucket,messagingSenderId,appId) are all part of the Firebase project configuration. These keys are required to initialize and authenticate our Firebase project when interacting with Firebase services on web platforms. ...
