Realtime JSON Update from Firebase to Component in FlutterFlow - RTDB Realtime Database

Custom Code

I'm working on a FlutterFlow project where I'm using Firebase Realtime Database to listen for updates to a JSON object. I've successfully implemented a listener that retrieves the data and prints it to the console in realtime. However, I'm struggling to figure out the best way to pass this JSON data to a specific component for realtime display.

Here's a summary of my situation:

  • The Firebase Realtime Database listener is working correctly, and I can see the data updates in the console.

  • I need to pass this JSON data to a specific component so that it updates in real-time whenever the database changes.

  • I'm having difficulty finding a way to efficiently update the component with the real-time data from the listener.

My Goal:

I want to achieve a real-time display of the JSON data within a specific component, ensuring that the component updates automatically whenever the database is modified, regardless of the source of the change.

Question:

What are the recommended approaches for passing realtime JSON data from a Firebase Realtime Database listener to a specific component in FlutterFlow? Are there any best practices or specific widgets that can help me achieve this?

Any help or guidance would be greatly appreciated!

What have you tried so far?
// Begin custom action code

// DO NOT REMOVE OR MODIFY THE CODE ABOVE!

import 'package:firebase_database/firebase_database.dart';



Future observeDataStream() async {

    final appInstance = Firebase.app("DataConnection");

    DatabaseReference dataStream =

        FirebaseDatabase.instanceFor(app: appInstance).ref("dataLocation");

    dataStream.onValue.listen((DatabaseEvent event) {

        final incomingData = event.snapshot.value as Map;

        print(incomingData['action']);

        print(incomingData['label']);

    });


// Set your action name, define your arguments and return parameter,

// and then add the boilerplate code using the green button on the right!
