My code looks like this. This is the function that is returning an object of MyUser.

class MyUser{
  final String name;
  String matric;
  final String email;
  final String userType;
  MyUser({
    required this.name, 
    this.matric='', 
    required this.email, 
    required this.userType});

  static Future<Object?> editProfile() async {
    return MyUser(name: 'name', email: 'email', userType: 'userType');
  }
}

And the code receiving it aims to print the received object of MyUser like so:

Future? editProfile() async {
      Object? userRes = await MyUser.editProfile();
      print(await userRes);
      return null;
    }

I want to print the object so I can use the keys to fetch values individually like user['name'] and it should print out name. But all I get is Instance of MyUser. Please help me out here. Thanks.

P.S: I want to know how to print objects like this on an async function.

CodePudding user response：

You should specify the right class, not just Object. then you can do this

static Future<MyUser> editProfile() async {
  return MyUser(name: 'name', email: 'email', userType: 'userType');
}

Future? editProfile() async {
  MyUser userRes = await MyUser.editProfile();
  print(userRes.name);
  return null;
}

CodePudding user response：

You can do like this to check all the fields of your custom data:

1. Your case

class MyUser{
  String name, email, userType;
  
  MyUser({required this.name, required this.email, required this.userType});

}

void main(){
  MyUser user = MyUser(name: 'test', email: '[email protected]', userType: 'test');
  print(user);
}

And output

Instance of 'MyUser'

2. New one

class MyUser{
  String name, email, userType;
  
  MyUser({required this.name, required this.email, required this.userType});
  
  @override
  String toString(){
    return 'name:'   name   ', email:'   email   ', userType:'   userType;
  }
}

void main(){
  MyUser user = MyUser(name: 'test', email: '[email protected]', userType: 'test');
  print(user);
}

And output

name:test, email:[email protected], userType:test
