How to Handle Firebase Auth exceptions on flutter

Question

Please does anyone know how to catch firebase Auth exceptions on flutter and display them?

Note: I am not interested in the console (catcherror((e) print(e))

Answer 1

in Dart you can react to different Exceptions using the on syntax. Since Firebase uses its own PlatformException you can easily catch them with:

  try {
      AuthResult result = await signUp(email, password);
  } on PlatformException catch (e) {
      print(e.message);
  } on Exception catch (e) {
      print(e);
  }

PlatformException brings a code as well as a message which can be displayed in the UI, i.e. :

PlatformException(ERROR_EMAIL_ALREADY_IN_USE, The email address is already in use by another account., null)
