Sign-out
Amplify provides a client library that enables you to interact with backend resources such as Amplify Auth.
To sign a user out of your application use the signOut API.
Future<void> signOutCurrentUser() async { final result = await Amplify.Auth.signOut(); if (result is CognitoCompleteSignOut) { safePrint('Sign out completed successfully'); } else if (result is CognitoFailedSignOut) { safePrint('Error signing user out: ${result.exception.message}'); }}You can also sign out users from all devices by performing a global sign-out. This will also invalidate all refresh tokens issued to a user. The user's current access and ID tokens will remain valid on other devices until the refresh token expires (access and ID tokens expire one hour after they are issued).
Future<void> signOutGlobally() async { final result = await Amplify.Auth.signOut( options: const SignOutOptions(globalSignOut: true), ); if (result is CognitoCompleteSignOut) { safePrint('Sign out completed successfully'); } else if (result is CognitoPartialSignOut) { final globalSignOutException = result.globalSignOutException!; final accessToken = globalSignOutException.accessToken; // Retry the global sign out using the access token, if desired // ... safePrint('Error signing user out: ${globalSignOutException.message}'); } else if (result is CognitoFailedSignOut) { safePrint('Error signing user out: ${result.exception.message}'); }}
