I TRIED USING MAP TO COLLECT DATA BUT IT DOESN'T WORK EITHER I AM TRYING TO GET LIST OF PRICE FROM REST API USING GETX IN FLUTTER BUT RESULTING TO THE ERROR BELOW SAYING CAST ERROR ON LOADING APP

CodePudding user response：

your jsonResponse is not List, it is Map, I call your request and it getting Unauthorized error. I think you should fix that first

CodePudding user response：

You are receiving a map and trying to parse in as a List. Thats what the error is telling you.

I would approach this by creating a model class for the and serialising the data there.

class User {
  final String name;
  final String email;

  User(this.name, this.email);

  User.fromJson(Map<String, dynamic> json)
      : name = json['name'],
        email = json['email'];

  Map<String, dynamic> toJson() => {
        'name': name,
        'email': email,
      };
}
