Depfile non valide: Flutter

Je suis un tutoriel d'un cours udemy et récemment j'ai construit un nouveau PC donc le disque dur qui stockait mon code est secondaire pour le moment. Lorsque je compile le code, cela me donne l'erreur suivante. Pour mieux l'expliquer, je poste une image d'un avertissement dans mon code, mais je suis presque sûr que c'est une erreur qui se produit, comme cela se produit habituellement avec les importations. Erreur dans le code J'ai essayé d'exécuter une application de test en créant une application par défaut à partir de cmd et cela fonctionne bien. Alors évidemment, Flutter Doctor ne montre aucune erreur. l'erreur est répétitive et longue, donc j'en colle une partie ci-dessous.

L'erreur-

Invalid depfile: D:\WorkSpace\Code\Flutter\Image App\image_app\.dart_tool\flutter_build\8f0d0eee9ef614ed024ca7691a333af8\kernel_snapshot.d
