Answer 1

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,
      };
}

example from flutter docs
