resolve LateInitializationError: Field '_userBiodata@48229069' has not been initialized-CodePudding

I have a problem when I fetch data using provider in Flutter.

I've tried changing it to NULL (UserBiodata?) without using LATE but the error occurs again in other parts.

Here is the code I wrote:

class UserBiodataProfile with ChangeNotifier {
  late UserBiodata _userBiodata;
  UserBiodata get userBiodata => _userBiodata;

  set userBiodata(UserBiodata newUserBiodata) {
    _userBiodata = newUserBiodata;
    notifyListeners();
  }
}

I call the data here:

Text(
  userBiodataProvider.userBiodata.data.name,
  style: bold5,
),

How do I solve it?

CodePudding user response：

While loding the data is null.

try this code

class UserBiodataProfile with ChangeNotifier {
  UserBiodata? _userBiodata;
  UserBiodata? get userBiodata => _userBiodata;

  set userBiodata(UserBiodata? newUserBiodata) {
    _userBiodata = newUserBiodata;
    notifyListeners();
  }
}

Text(
userBiodataProvider.userBiodata == null ?  "" : 
userBiodataProvider.userBiodata.data.name,
style: bold5,
),

CodePudding user response：

Try the following code:

final UserBiodata userBiodata = UserBiodata(
  status: …,
  code: …,
  data: …,
);

Text(
  userBiodata.data.name,
  style: bold5,
),
