EmailAuthController class

Controller for managing email-based authentication flows.

This controller handles all the business logic for email authentication, including login, registration, and email verification. It can be used with any UI implementation.

Example usage:

final controller = EmailAuthController(
  client: client,
  onAuthenticated: () {
    // Do something when the user is authenticated.
    //
    // NOTE: You should not navigate to the home screen here, otherwise
    // the user will have to sign in again every time they open the app.
  },
);

// Login
await controller.login();

// Start registration
await controller.startRegistration();

// Finish registration
await controller.finishRegistration();

// Listen to state changes
controller.addListener(() {
  // UI will rebuild automatically
  // Can use `controller.state` to access the current state.
});
