try{
final response = await http.get(url+userID);
return Result<UserModel>(data: UserMode.fromJson(response.data),);
} catch(e){
return Result(error: ErrorResult(message: "User data not avaible"),);
}
}

Example in use (normaly in Controller)
getUserData (String userID)async{
Result<UserModel> result = await UsersService().getUserData(userID);
result.fold(
onSuccess: (data){
loggedUser = data;
notifyListeners();
//navigate to home or other actions
},
onError: (error){
//function to show the error, take the user to register ou logOut
}
);
