Create and read a user¶

Use the generated repository to create one user and read it back. Replace the contents of bin/dorm_store.dart with this complete application:

import 'package:dorm_memory_database/dorm_memory_database.dart';

import 'package:dorm_store/models.dart';

Future<void> main() async {
  final dorm = Dorm(Engine());
  final User created = await dorm.users.repository.put(
    Creation.auto(
      dependency: UserDependency(),
      data: UserData(
        username: 'ada',
        email: 'ada@example.com',
        profile: Profile(
          name: 'Ada Lovelace',
          birthDate: DateTime(1815, 12, 10),
          bio: null,
        ),
      ),
    ),
  );
  final User? loaded = await dorm.users.repository.peek(created.id);

  print(loaded?.email ?? 'User not found');
}

put receives a Creation object. Creation.auto follows the identity strategy declared by the model and carries the dependency and data used to construct it. The returned User is already identified, so its id can be passed to peek. peek returns null when that identity is not present.

Run the application¶

Run the generation command again after changing models.dart, then start the application:

dart run build_runner build
dart run

The program prints the email read from the repository. The records live only for the lifetime of this process because the in-memory engine is in-process.

Continue the example with carts and cart items, then use Operations for the reusable create, read, update, delete, filter, sorting, and pagination tasks.
