Commencez par comparer la version de Flutter utilisée avec le code de navigation et de dialogue référencé dans main.dart:27 et managers/dialog_manager.dart. Reproduisez l’échec du formulaire d’inscription, examinez la frame de pile _DialogManagerState._showDialog et l’instruction de retour de pop(), puis confirmez que les services de navigation et de dialogue fonctionnent sans l’assertion de booléen nul.

Rédigé par le modèle d'indexation à partir du texte de l'issue.
