Project not connecting to real time database - flutter

Question

I am having a problem with real time database not working, I copied a project from GitHub and made a new project in firebase with my app ID, added the JSON file to my app and changed the write and read rules to true but still not working or showing anything in the terminal

source code :

import 'package:firebase_core/firebase_core.dart';
import 'package:firebase_database/firebase_database.dart';
import 'package:flutter/cupertino.dart';
import 'package:flutter/material.dart';
import 'package:flutter/rendering.dart';

class CustomData extends StatefulWidget {
  CustomData({this.app});
  final FirebaseApp app;
  @override
  _CustomDataState createState() => _CustomDataState();
}

class _CustomDataState extends State<CustomData> {
  final refrenceDatabase = FirebaseDatabase.instance;
  final MovieController  = TextEditingController();

  @override
  Widget build(BuildContext context) {
    final ref = refrenceDatabase.reference();
    return Scaffold(
      appBar: AppBar(title: Text('Real Time DataBase'),backgroundColor: Colors.red,),
      backgroundColor: CupertinoColors.systemGrey,
      body: SingleChildScrollView(
        child: Column(children: [
          Center(child:
          Container(
            color: Colors.blue,
            width: MediaQuery.of(context).size.width,
            height: MediaQuery.of(context).size.height,
            child: Column(
              children: [
                Text('Movie title',style: TextStyle(fontSize: 25, fontWeight: FontWeight.bold), textAlign: TextAlign.center,),
                TextField(controller: MovireController, textAlign: TextAlign.center,),
                FlatButton(
                  color: Colors.orange,
                    onPressed: (){
                  ref.child('Movies').push().child('movie title').set(MovieController).asStream();
                }, child: Text('Submit'))
              ],
            ),

          ),)
        ],),
      ),
    );
  }
}

Database rules:

{
  "rules": {
    ".read": true,  // 2021-3-23
    ".write": true,  // 2021-3-23
  }
}

Answer 1

Ok. So, from what I have seen, you do not receive any errors. So, it means that your firebase is connecting properly. The second thing is the following error in the code. I don't know what you expect to do with the following code but it is not correct.

// Firstly, you're passing a TextEditingController instead of a string.
// Secondly, you're streaming data but you're not accessing it anywhere.
ref.child('Movies').push().child('movie title').set(MovieController).asStream();

ref.child('Movies').push().set({
  "movie title": MovieController.text,
});

This should push data to your Database.
