Improvement custom field

[Rodrigolmti]

Hi, this is a great package thanks for sharing. I did look at the documentation and did not see anything like...

For example, I have the class

class UserResponse { final String profile; ... }

And I have

enum UserProfile { investor, consumer }

class User {
final UserProfile profile;
...
}

How can I make the mapper to map with a custom logic for example:

profile: enumFromString<UserProfile>(
    UserProfile.values,
    response.profile,
    UserProfile.consumer,
  )

for the profile field. This is just one example there is several more like

class UserResponse {
   final String zipCode;
   final String number;
   final String street;
...
}

Map to

class User {
   final Address address;
}

Hi @Rodrigolmti
I like the idea, I was thinking of something like

@Mapper()
class UserResponseMapper{
    @Mapping(source: 'zipCode', target: 'response.address.zipCode')
    User fromUserResponse(UserResponse response);
}

The mapper could automatically determine the address field in the Target User Object, and map the fields according to the configuration. See also https://mapstruct.org/documentation/dev/reference/html/#mappings-with-several-source-parameters

Right now as a workaround, you could try providing multiple mapper methods, so the desired mapper method can automatically map the nested bean.

@Mapper()
class UserMapper {
  User fromUserResponse(UserResponse response);
  Address fromUserResponseAddress(UserResponse response);
}

The fromUserResponse would now automatically call the fromUserResponseAddress to map its Address. See also https://github.com/smotastic/smartstruct/blob/master/example/lib/nested/nested.dart

I'll see what I can do, or if you feel like it, feel free to open a PR

Hi, I just merged this feature.

Now you can write something like this

@Mapper()
abstract class UserMapper {
  @Mapping(target: 'zipcode', source: 'response.address.zipcode')
  @Mapping(target: 'street', source: 'response.address.street.streetName')
  User fromResponse(UserResponse response);
}

To directly map nested models in the mapper.
