Test for requires-recent-login throw programmatically

[FMorschel]

Copied from firebase/flutterfire#11730

On firebase_auth there is a FirebaseAuthException with code "requires-recent-login". I believe it would be useful to have a method to test if this would be thrown on trying to work with security-sensitive actions.

For example, with firebase_ui_auth, when I call EmailSignUpDialog it throws the warning there. I would love for it to show my users that they need to reauthenticate before opening that dialog.

Could you please provide more details on what's expected?

when I call EmailSignUpDialog it throws the warning there

I'm not sure I understand what it means.

When I use EmailSignUpDialog, I need to wrap it in a FirebaseUIActions with an AuthStateChangeAction<AuthFailed> like the following code:

FirebaseUIActions(
  actions: [
    AuthStateChangeAction<AuthFailed>((context, state) {
      final exception = state.exception;
      if (exception is FirebaseAuthException) {
        if (exception.code == 'requires-recent-login') {
          showReauthenticateDialog(
            context: context,
            providers: linkedProviders(),
          );
        }
      }
    }),
  ],
  child: EmailSignUpDialog(
    provider: provider as EmailAuthProvider,
    action: AuthAction.link,
    showPasswordVisibilityToggle: true,
  ),
)

Now, as I asked above;

I would love for it to show my users that they need to reauthenticate before opening that dialog.

Not by throwing inside when the user tries to link the new provider. I want to ask the person to reauthenticate just before opening the dialog. For example by executing a FirebaseAuth.instance.needsReauthentication() or something similar.
