Comment réparer «Échec de l'exécution de la tâche ': app: processDebugResources'.> Échec de la liaison des ressources Android» [Android / Flutter]

C'est arrivé de nulle part. Un jour, j'exécutais mon code qui fonctionnait très bien, et le lendemain, sans toucher à mes fichiers build.gradle ou à tout autre fichier de construction, cette erreur est apparue.

J'ai essayé beaucoup de solutions différentes comme changer ma buildToolsVersion ou en définissant un indicateur spécifique d'AAPT (je ne me souviens plus lequel) sur false. Rien ne fonctionne. Mon fichier app \ build.gradle:

Execution failed for task ':app:processDebugResources'.
