Prasyarat
Instal firebase_core dan tambahkan kode inisialisasi ke aplikasi Anda jika belum melakukannya.
Tambahkan aplikasi Anda ke project Firebase di Firebase console.
Membuat Database
Buka bagian Realtime Database di Firebase console.
Anda akan diminta untuk memilih project Firebase yang ada.
Ikuti alur kerja pembuatan database.
Pilih mode awal untuk aturan keamanan Anda:
Mode pengujian
Cocok untuk memulai dengan library klien seluler dan web, tetapi memungkinkan siapa pun untuk membaca dan menimpa data Anda. Setelah melakukan pengujian, pastikan untuk meninjau bagian Memahami Aturan Firebase Realtime Database.
Untuk memulai, pilih mode pengujian.
Mode terkunci
Menolak semua pembacaan dan penulisan dari klien seluler dan web.
Server aplikasi terautentikasi Anda masih dapat mengakses database Anda.
Pilih region untuk database. Bergantung pada pilihan region, namespace database akan dalam format <databaseName>.firebaseio.com atau <databaseName>.<region>.firebasedatabase.app. Untuk informasi selengkapnya, lihat memilih lokasi untuk project Anda.
Klik Done.
Saat Anda mengaktifkan Realtime Database, API di Pengelola Cloud API juga akan aktif.
Menambahkan Firebase Realtime Database ke aplikasi
Dari root project Flutter Anda, jalankan perintah berikut untuk menginstal plugin:
flutterpubaddfirebase_database
Setelah selesai, bangun ulang aplikasi Flutter Anda:
flutterrun
Mengonfigurasi aturan database
Realtime Database menyediakan bahasa aturan deklaratif, sehingga Anda dapat menentukan cara data disusun, diindeks, serta kapan data tersebut dapat dibaca dan ditulisi.
Melakukan inisialisasi paket Firebase Realtime Database
Untuk mulai menggunakan paket Realtime Database dalam project Anda, impor paket tersebut di bagian atas file project Anda:

[Install `firebase_core`](/docs/flutter/setup) and add the initialization code to your app if you haven't already.\n2. Add your app to your Firebase project in the [Firebase console](https://console.firebase.google.com/).\n\nCreate a Database\n\n1. Navigate to the **Realtime Database** section of the [Firebase console](https://console.firebase.google.com/project/_/database).\n You'll be prompted to select an existing Firebase project.\n Follow the database creation workflow.\n\n2. Select a starting mode for your security rules:\n\n **Test mode**\n\n Good for getting started with the mobile and web client libraries,\n but allows anyone to read and overwrite your data. After testing, **make\n sure to review the [Understand Firebase Realtime Database Rules](/docs/database/security)\n section.**\n | **Note:** If you create a database in Test mode and make no changes to the default world-readable and world-writeable security rules within a trial period, you will be alerted by email, then your database rules will deny all requests. Note the expiration date during the Firebase console setup flow.\n\n To get started, select testmode.\n\n **Locked mode**\n\n Denies all reads and writes from mobile and web clients.\n Your authenticated application servers can still access your database.\n3. Choose a region for the database. Depending on your choice of region,\n the database namespace will be of the form `\u003cdatabaseName\u003e.firebaseio.com` or\n `\u003cdatabaseName\u003e.\u003cregion\u003e.firebasedatabase.app`. For more information, see\n [select locations for your project](/docs/projects/locations#rtdb-locations).\n\n4. Click **Done**.\n\nWhen you enable Realtime Database, it also enables the API in the\n[Cloud API Manager](https://console.cloud.google.com/projectselector/apis/api/firebasedatabase.googleapis.com/overview).\n\nAdd Firebase Realtime Database to your app\n\n1. From the root of your Flutter project, run the following command to install the plugin:\n\n flutter pub add firebase_database\n\n2. Once complete, rebuild your Flutter application:\n\n flutter run\n\nConfigure database rules\n\nThe Realtime Database provides a declarative rules language that allows you to\ndefine how your data should be structured, how it should be indexed, and when\nyour data can be read from and written to.\n| **Note:** By default, read and write access to your database is restricted so only authenticated users can read or write data. To get started without setting up Firebase Authentication, you can [configure your rules for public access](/docs/rules/basics#default_rules_locked_mode). This does make your database open to anyone, even people not using your app, so be sure to restrict your database again when you set up authentication.\n\nInitialize the Firebase Realtime Database package\n\nTo start using the Realtime Database package within your project, import it at\nthe top of your project files: \n\n import 'package:firebase_database/firebase_database.dart';\n\nTo use the default Database instance, call the `instance`\ngetter on `FirebaseDatabase`: \n\n FirebaseDatabase database = FirebaseDatabase.instance;\n\nIf you'd like to use it with a secondary Firebase App, use the static `instanceFor` method: \n\n FirebaseApp secondaryApp = Firebase.app('SecondaryApp');\n FirebaseDatabase database = FirebaseDatabase.instanceFor(app: secondaryApp);\n\nIf you'd like to use a different RTDB instance on the same project, you can pass in a `databaseUrl` using\nthe static `instanceFor` method: \n\n final firebaseApp = Firebase.app();\n final rtdb = FirebaseDatabase.instanceFor(app: firebaseApp, databaseURL: 'https://your-realtime-database-url.firebaseio.com/');\n\nNext Steps\n\n- Learn how to [structure data](/docs/database/flutter/structure-data) for Realtime Database.\n\n- [Scale your data across multiple database instances.](/docs/database/usage/sharding)\n\n- [Read and write data.](/docs/database/flutter/read-and-write)\n\n- [View your database in the\n Firebase console.](//console.firebase.google.com/project/_/database/data)"]]
