Symboles non définis pour l'architecture x86_64 flotter

Question

Je travaille dans une application flotte. =Android Travailler bien, mais dans iOS non. J'ai besoin d'aide pour exécuter cela sur iOS mobile. J'utilise lib: - (google_maps_flutter: ^ 0.5.27 + et FireBase_ML_Vision: ^ 0.9.3 + 8. Xcode 11.4.1 et Mac OS Catalina 10.15.4. Quelqu'un sait comment résoudre ce problème. Je n'ai pas encore trouvé.

L'erreur est probablement sur certains des fichiers de projet Xcode, essayez:

Faites une sauvegarde de votre projet.
Exécuter cette commande

flutter propre &&\ rm ios/podfile ios/podfile.lock pubspec.lock && m -rf ios/pods ios/runner.xckspaceSpace &&\flutter gui

Il s'agit souvent d'une question de résolution de dépendance dû à la mise en cache existante. Si vous ne pouvez pas construire pour iOS, quelle que soit la version du plugin, procédez comme suit.

Remarque: Il est recommandé de le faire de temps en temps et qu'il se débarrasse également de nombreux espaces utilisés sur votre machine.

Sur project/ios Dossier, Run pod deintegrate && rm Podfile.lock && pod install
Sur votre dossier de projet, exécutez flutter clean
Effacez les données dérivées Xcode en exécutant rm -rf ~/Library/Developer/Xcode/DerivedData
Ouvrez le projet avec Xcode et aussi propre en faisant Cmd + Shift + K
Construire avec flutter build ios commande.
