ERREUR: flutter / lib / ui / ui_Dart_state.cc (148) Exception non gérée

Obtenir cette erreur au démarrage de l'application. Au départ, je pensais que c'était un problème de migration vers AndroidX , j'ai fait toutes les étapes pour migrer vers la bibliothèque de support androidx, en vain.

  1. Publié un problème Github ici
  2. J'ai cherché de l'aide dans les commentaires sur problème similaire .

Impossible de déboguer car j'obtiens cette erreur avant le point d'arrêt à la première ligne des hits de la fonction principale.

Il s'agit d'une erreur de non-concordance de type, assurez-vous que votre type de retour est le même que le type de variable

Veuillez vérifier le type de demande, que ce soit GET ou POST. Si vous appelez get request for post request, il affiche cette erreur. Si le type de demande est correct, veuillez vérifier votre réponse JSON, qu'elle soit au format JSON ou non. J'espère que ça aide.
