CodePudding user response：

Could you further specify what it is that you get as a result? Is the whole list full of null? Or are some of the objects' fields null?

Here is what I believe is an error:

nameUser: json['tenNguoiDung'] == null ? '' : json['ten']
avatarUser: json['nguoiDung_anhDinhKem'] == null ? '' : json['avatar'],

You are saying:

If tenNguoiDung is null: nameUser is equal to '', if it isn't, nameUser = json['ten'].

But your json doesn't have a 'ten' field, so it will be null. What you are most likely looking for is the if-null operator:

nameUser: json['tenNguoiDung'] ?? ''
avatarUser: json['nguoiDung_anhDinhKem'] ?? ''

which will assign '' if the json field is null.
