supabase-dart

A Dart client for Supabase.

Note

If you are developing a Flutter application, use supabase_flutter instead. supabase package is for non-Flutter Dart environments.

What is Supabase

Supabase is an open source Firebase alternative. We are a service to:

• listen to database changes
• query your tables, including filtering, pagination, and deeply nested relationships (like GraphQL)
• create, update, and delete rows
• manage your users and their permissions
• interact with your database using a simple UI

Status

Public Beta: Stable. No breaking changes expected in this version but possible bugs.

Usage example

Database

import 'package:supabase/supabase.dart';

main() {
  final supabase = SupabaseClient('supabaseUrl', 'supabaseKey');

  // Select from table `countries` ordering by `name`
  final data = await supabase
      .from('countries')
      .select()
      .order('name', ascending: true);
}

Realtime

import 'package:supabase/supabase.dart';

main() {
  final supabase = SupabaseClient('supabaseUrl', 'supabaseKey');

  // Set up a listener to listen to changes in `countries` table
  supabase.channel('my_channel').on(RealtimeListenTypes.postgresChanges, ChannelFilter(
      event: '*',
      schema: 'public',
      table: 'countries'
    ), (payload, [ref]) {
      // Do something when there is an update
    }).subscribe();

  // remember to remove the channels when you're done
  supabase.removeAllChannels();
}

Realtime data as Stream

To receive realtime updates, you have to first enable Realtime on from your Supabase console. You can read more here on how to enable it.

import 'package:supabase/supabase.dart';

main() {
  final supabase = SupabaseClient('supabaseUrl', 'supabaseKey');

  // Set up a listener to listen to changes in `countries` table
  final subscription = supabase
      .from('countries')
      .stream(primaryKey: ['id']) // Pass list of primary key column names
      .order('name')
      .limit(30)
      .listen(_handleCountriesStream);

  // remember to remove subscription when you're done
  subscription.cancel();
}

Authentication

This package does not persist auth state automatically. Use supabase_flutter for Flutter apps to persist auth state instead of this package.

import 'package:supabase/supabase.dart';

main() {
  final supabase = SupabaseClient('supabaseUrl', 'supabaseKey');

  // Sign up user with email and password
  final response = await supabase
    .auth
    .signUp(email: '[email protected]', password: 'password');
}

Storage

import 'package:supabase/supabase.dart';

main() {
  final supabase = SupabaseClient('supabaseUrl', 'supabaseKey');

  // Create file `example.txt` and upload it in `public` bucket
  final file = File('example.txt');
  file.writeAsStringSync('File content');
  final storageResponse = await supabase
      .storage
      .from('public')
      .upload('example.txt', file);
}
