NyFactory class

Laravel-style model factories for testing.

This class allows you to define factories for creating test data with sensible defaults and overrideable attributes.

Example:

// Define a factory
NyFactory.define<User>((faker) => User(
  id: faker.randomInt(1, 1000),
  name: faker.name(),
  email: faker.email(),
));

// Create instances
final user = NyFactory.make<User>();
final users = NyFactory.create<User>(count: 5);

// With overrides
final admin = NyFactory.make<User>(overrides: {'role': 'admin'});
