mapify

Description:

mapify

A flutter plugin for mapping objects #
This library helps mapping similar objects to eachother.
While implementing clean architecture principles significantly improves code maintenability and readability
you might find yourself repeating class structures over several layers.
This library generates extensions based on the original input object to the desired output, and automatically resolves matching fields.
Usage #
Let's consider the following input object:
class Account {
final String id;
final List<String> activeMemberIds;
final List<Member> members;

const Account({
required this.id,
required this.activeMemberIds,
required this.members,
});
}
copied to clipboard
We have the following output objects in other packages of our main app:
class AccountEntity {
final String id;
final List<String> activeMemberIds;
final List<Member> members;

const AccountEntity({
required this.id,
required this.activeMemberIds,
required this.members,
});
}

class AccountDto {
final String id;
final List<String> activeMemberIds;
final List<MemberDto> members;

const AccountDto({
required this.id,
required this.activeMemberIds,
required this.members,
});
}
copied to clipboard
To generate the required mapping, we define a new dart file, and put the following code:

import 'package:example_api/example_api.dart';
import 'package:example_core/example_core.dart';
import 'package:mapify/mapify.dart';

/// Add child mapper files if there are dependencies
import 'member.dart';

part 'account.g.dart';

@GenerateMapping(
outputType: [
AccountDto,
AccountEntity,
],
inputType: Account,
)
class AccountMapper extends MappingManager<Account> {
AccountMapper(super.input);
}

copied to clipboard
Now run the build_runner: flutter pub run build_runner build --delete-conflicting-outputs in the project that includes the account mapper, and the mapping
will be generated
