Il semble que le problème soit là: [ERREUR: flutter/lib/ui/ui_Dart_state.cc (148)] Exception non gérée: MissingPluginException (Aucune implémentation trouvée pour la méthode getApplicationDocumentsDirectory sur le canal plugins.flutter.io/path_provider)

Déjà fait ceci:

-Supprimé tous les plugins et réinstallé avec flutter pub get.
- Exécutée flutter clean et flutter run

Il s'est avéré que je devais quitter le processus de flutter et le redémarrer. Un redémarrage complet au cours de l'exécution de flottement n'a pas fonctionné.

Voici un lien de référence https://github.com/flutter/flutter/issues/10912

Modifier: assurez-vous d'importer ces packages;

package: path_provider/path_provider.Dart
Fléchette: io
Dart: async
