magic_sdk 5.0.0

This is your entry-point to secure, passwordless authentication for your iOS or Android-based Flutter app.

Magic empowers developers to protect their users via an innovative, passwordless authentication flow without the UX compromises that burden traditional OAuth implementations.

⚠️ Removal of loginWithMagicLink() ⚠️

As of v4.0.0, passcodes (ie. loginWithSMS(), loginWithEmailOTP()) are replacing Magic Links (ie. loginWithMagicLink()) for all of our Mobile SDKs⁠. Learn more

Features

This is your entry-point to secure, passwordless authentication for your iOS or Android-based Flutter app.

Installation

Add magic_sdk to your pubspec.yaml:

dependencies:
  flutter:
    sdk: flutter
  magic_sdk: ^4.0.0

Run the following command to install dependencies

$ dart pub get

Create an SDK Instance

In main.dart, instantiate Magic with your publishable key

void main() {
  runApp(const MyApp());

  Magic.instance = Magic("YOUR_PUBLISHABLE_KEY");
}

Use Stack in the top level and add Magic.instance.relayer to the children of Stack to ensure the best performance

Note: Relayer is required to establish communication between apps and Magic service. Make sure to have it in a stack whenever you need to authenticate or interact with blockchain

class MyApp extends StatelessWidget {
  const MyApp({Key? key}) : super(key: key);

  // This widget is the root of your application.
  @override
  Widget build(BuildContext context) {
    @override
    Widget build(BuildContext context) {
      return MaterialApp(
          title: 'Magic Demo',
          home: Stack(children: [
            const LoginPage(),
            Magic.instance.relayer
          ]));
    }
  }
}

Authenticate your first user!

var token = await magic.auth.loginWithEmailOTP(email: textController.text);
