Build a User Management App with Flutter

This tutorial demonstrates how to build a basic user management app. The app authenticates and identifies the user, stores their profile information in the database, and allows the user to log in, update their profile details, and upload a profile photo. The app uses:

Supabase Database - a Postgres database for storing your user data and Row Level Security so data is protected and users can only access their own information.
Supabase Auth - users log in through magic links sent to their email (without having to set up passwords).
Supabase Storage - users can upload a profile photo.

Supabase User Management example

If you get stuck while working through this guide, refer to the full example on GitHub.

Project setup

Before we start building we're going to set up our Database and API. This is as simple as starting a new Project in Supabase and then creating a "schema" inside the database.

Create a project

Create a new project in the Supabase Dashboard.
Enter your project details.
Wait for the new database to launch.

Set up the database schema

Now we are going to set up the database schema. We can use the "User Management Starter" quickstart in the SQL Editor, or you can just copy/paste the SQL from below and run it yourself.

Go to the SQL Editor page in the Dashboard.
Click User Management Starter.
Click Run.

You can easily pull the database schema down to your local project by running the db pull command. Read the local development docs for detailed instructions.


_10supabase link --project-ref <project-id>
_10# You can get <project-id> from your project's dashboard URL: https://supabase.com/dashboard/project/<project-id>
_10supabase db pull

Get the API Keys

Now that you've created some database tables, you are ready to insert data using the auto-generated API. We just need to get the Project URL and anon key from the API settings.

Go to the API Settings page in the Dashboard.
Find your Project URL, anon, and service_role keys on this page.

Building the app

Let's start building the Flutter app from scratch.

Initialize a Flutter app

We can use flutter create to initialize an app called supabase_quickstart:


_10flutter create supabase_quickstart

Then let's install the only additional dependency: supabase_flutter

Copy and paste the following line in your pubspec.yaml to install the package:


_10supabase_flutter: ^2.0.0

Run flutter pub get to install the dependencies.

Setup deep links

Now that we have the dependencies installed let's setup deep links. Setting up deep links is required to bring back the user to the app when they click on the magic link to sign in. We can setup deep links with just a minor tweak on our Flutter application.

We have to use io.supabase.flutterquickstart as the scheme. In this example, we will use login-callback as the host for our deep link, but you can change it to whatever you would like.

First, add io.supabase.flutterquickstart://login-callback/ as a new redirect URL in the Dashboard.

Supabase console deep link setting

That is it on Supabase's end and the rest are platform specific settings:

Edit the ios/Runner/Info.plist file.

Add CFBundleURLTypes to enable deep linking:

ios/Runner/Info.plist"


_20<!-- ... other tags -->
_20<plist>
_20<dict>
_20  <!-- ... other tags -->
_20
_20  <!-- Add this array for Deep Links -->
_20  <key>CFBundleURLTypes</key>
_20  <array>
_20    <dict>
_20      <key>CFBundleTypeRole</key>
_20      <string>Editor</string>
_20      <key>CFBundleURLSchemes</key>
_20      <array>
_20        <string>io.supabase.flutterquickstart</string>
_20      </array>
_20    </dict>
_20  </array>
_20  <!-- ... other tags -->
_20</dict>
_20</plist>

Main function

Now that we have deep links ready let's initialize the Supabase client inside our main function with the API credentials that you copied earlier. These variables will be exposed on the app, and that's completely fine since we have Row Level Security enabled on our Database.

lib/main.dart


_21import 'package:flutter/material.dart';
_21import 'package:supabase_flutter/supabase_flutter.dart';
_21
_21Future<void> main() async {
_21  await Supabase.initialize(
_21    url: 'YOUR_SUPABASE_URL',
_21    anonKey: 'YOUR_SUPABASE_ANON_KEY',
_21  );
_21  runApp(const MyApp());
_21}
_21
_21final supabase = Supabase.instance.client;
_21
_21class MyApp extends StatelessWidget {
_21  const MyApp({super.key});
_21
_21  @override
_21  Widget build(BuildContext context) {
_21    return const MaterialApp(title: 'Supabase Flutter');
_21  }
_21}

Set up splash screen

Let's create a splash screen that will be shown to users right after they open the app. This screen retrieves the current session and redirects the user accordingly.

lib/pages/splash_page.dart


_38import 'package:flutter/material.dart';
_38import 'package:supabase_quickstart/main.dart';
_38
_38class SplashPage extends StatefulWidget {
_38  const SplashPage({super.key});
_38
_38  @override
_38  State<SplashPage> createState() => _SplashPageState();
_38}
_38
_38class _SplashPageState extends State<SplashPage> {
_38  @override
_38  void initState() {
_38    super.initState();
_38    _redirect();
_38  }
_38
_38  Future<void> _redirect() async {
_38    await Future.delayed(Duration.zero);
_38    if (!mounted) {
_38      return;
_38    }
_38
_38    final session = supabase.auth.currentSession;
_38    if (session != null) {
_38      Navigator.of(context).pushReplacementNamed('/account');
_38    } else {
_38      Navigator.of(context).pushReplacementNamed('/login');
_38    }
_38  }
_38
_38  @override
_38  Widget build(BuildContext context) {
_38    return const Scaffold(
_38      body: Center(child: CircularProgressIndicator()),
_38    );
_38  }
_38}

Let's create a Flutter widget to manage logins and sign ups. We'll use Magic Links, so users can sign in with their email without using passwords. Notice that this page sets up a listener on the user's auth state using onAuthStateChange. A new event will fire when the user comes back to the app by clicking their magic link, which this page can catch and redirect the user accordingly.

lib/pages/login_page.dart

_102      });
_102      await supabase.auth.signInWithOtp(
_102        email: _emailController.text.trim(),
_102        emailRedirectTo:

_102        );
_102        _emailController.clear();
_102      }
_102    } on AuthException catch (error) {

_102        );
_102      }
_102    } catch (error) {
_102      if (mounted) {
_102        SnackBar(

_102        );
_102      }
_102    } finally {
_102      if (mounted) {
_102        setState(() {
_102          _isLoading = false;
_102        });
_102      }
_102    }
_102  }
_102
_102  @override
_102  void initState() {
_102    _authStateSubscription = supabase.auth.onAuthStateChange.listen((data) {
_102      if (_redirecting) return;
_102      final session = data.session;
_102      if (session != null) {
_102        _redirecting = true;
_102        Navigator.of(context).pushReplacementNamed('/account');
_102      }
_102    });
_102    super.initState();
_102  }
_102
_102  @override
_102  void dispose() {
_102    _emailController.dispose();
_102    _authStateSubscription.cancel();
_102    super.dispose();
_102  }
_102
_102  @override
_102  Widget build(BuildContext context) {
_102    return Scaffold(
_102      appBar: AppBar(title: const Text('Sign In')),
_102      body: ListView(
_102        padding: const EdgeInsets.symmetric(vertical: 18, horizontal: 12),
_102        children: [
_102          const Text('Sign in via the magic link with your email below'),
_102          const SizedBox(height: 18),
_102          TextFormField(
_102            controller: _emailController,
_102            decoration: const InputDecoration(labelText: 'Email'),
_102          ),
_102          const SizedBox(height: 18),
_102          ElevatedButton(
_102            onPressed: _isLoading ? null : _signIn,
_102            child: Text(_isLoading ? 'Loading' : 'Send Magic Link'),
_102          ),
_102        ],
_102      ),
_102    );
_102  }
_102}

Set up account page

After a user is signed in we can allow them to edit their profile details and manage their account. Let's create a new widget called account_page.dart for that.

_163    );
_163  }

Launch!

Now that we have all the components in place, let's update lib/main.dart:

lib/main.dart


_46import 'package:flutter/material.dart';
_46import 'package:supabase_flutter/supabase_flutter.dart';
_46import 'package:supabase_quickstart/pages/account_page.dart';
_46import 'package:supabase_quickstart/pages/login_page.dart';
_46import 'package:supabase_quickstart/pages/splash_page.dart';
_46
_46Future<void> main() async {
_46  await Supabase.initialize(
_46    url: 'YOUR_SUPABASE_URL',
_46    anonKey: 'YOUR_SUPABASE_ANON_KEY',
_46  );
_46  runApp(const MyApp());
_46}
_46
_46final supabase = Supabase.instance.client;
_46
_46class MyApp extends StatelessWidget {
_46  const MyApp({super.key});
_46
_46  @override
_46  Widget build(BuildContext context) {
_46    return MaterialApp(
_46      title: 'Supabase Flutter',
_46      theme: ThemeData.dark().copyWith(
_46        primaryColor: Colors.green,
_46        textButtonTheme: TextButtonThemeData(
_46          style: TextButton.styleFrom(
_46            foregroundColor: Colors.green,
_46          ),
_46        ),
_46        elevatedButtonTheme: ElevatedButtonThemeData(
_46          style: ElevatedButton.styleFrom(
_46            foregroundColor: Colors.white,
_46            backgroundColor: Colors.green,
_46          ),
_46        ),
_46      ),
_46      initialRoute: '/',
_46      routes: <String, WidgetBuilder>{
_46        '/': (_) => const SplashPage(),
_46        '/login': (_) => const LoginPage(),
_46        '/account': (_) => const AccountPage(),
_46      },
_46    );
_46  }
_46}

Once that's done, run this in a terminal window to launch on Android or iOS:


_10flutter run

Or for web, run the following command to launch it on localhost:3000


_10flutter run -d web-server --web-hostname localhost --web-port 3000

And then open the browser to localhost:3000 and you should see the completed app.

Supabase User Management example

Bonus: Profile photos

Every Supabase project is configured with Storage for managing large files like photos and videos.

Making sure we have a public bucket

We will be storing the image as a publicly sharable image. Make sure your avatars bucket is set to public, and if it is not, change the publicity by clicking the dot menu that appears when you hover over the bucket name. You should see an orange Public badge next to your bucket name if your bucket is set to public.

Adding image uploading feature to account page

We will use image_picker plugin to select an image from the device.

Add the following line in your pubspec.yaml file to install image_picker:


_10image_picker: ^1.0.5

Using image_picker requires some additional preparation depending on the platform. Follow the instruction on README.md of image_picker on how to set it up for the platform you are using.

Once you are done with all of the above, it is time to dive into coding.

Let's create an avatar for the user so that they can upload a profile photo. We can start by creating a new component:
