Hello, I'd like to share my experience setting up Firebase with Flutter. This is a simple setup guide that doesn't cover a large project, as the main focus here is specifically on integrating Flutter and Firebase.

1. FIREBASE FLUTTER SETUP
2. Login Firebase Console
3. Create project FLUTTER

After that follow this instruction bellows:

• Create Project on Firebase (choose apps) and follow the instuction
• Setup firebase_core:

<aside> 💡

flutter pub get firebase_core

flutter pub add firebase_core

flutter pub get

</aside>

• Edit on main.dart

<aside> 💡

import 'package:firebase_core/firebase_core.dart'; //optional

WidgetsFlutterBinding.ensureInitialized();
  await Firebase.initializeApp(
    options: DefaultFirebaseOptions.currentPlatform,
  );
  print('Firebase initialized!');
  runApp(MyApp());

</aside>

• IF errors? install firebase CLI

<aside> 💡

npm install -g firebase-tools

add fluterfire into env

dart pub global activate flutterfire_cli

flutterfire config

flutterfire login (if needed)

</aside>

SETUP DATABASE FIREBASE

• Create Realtime database for example:

example setup firebase

• After that run this command on terminal:

<aside> 💡

flutter pub add firebase_database

</aside>

• If error, make sure the url databse added on the firebase_optional.dart, if didn’t run:

<aside> 💡

Add manualy on file code ‘firebase_optional.dart’

or

ReRun ‘flutterfire config’ and select the database (follow the instructions).
