Listen to auth events

AWS Cognito Auth Plugin sends important events through Amplify Hub.

Amplify Flutter v1 is now in Maintenance Mode until April 30th, 2025. This means that we will continue to include updates to ensure compatibility with backend services and security. No new features will be introduced in v1.

Please use the latest version (v2) of Amplify Flutter to get started.

If you are currently using v1, follow these instructions to upgrade to v2.

final subscription = Amplify.Hub.listen(HubChannel.Auth, (AuthHubEvent event) {
  switch (event.type) {
    case AuthHubEventType.signedIn:
      safePrint('User is signed in.');
      break;
    case AuthHubEventType.signedOut:
      safePrint('User is signed out.');
      break;
    case AuthHubEventType.sessionExpired:
      safePrint('The session has expired.');
      break;
    case AuthHubEventType.userDeleted:
      safePrint('The user has been deleted.');
      break;
