fabrik_result

fabrik_result is a minimal and lightweight result-handling toolkit for real-world Dart and Flutter apps.

---

Features

• ✅ A sealed Either<L, R> type to model success/failure without using try-catch
• 🎯 A Unit type to represent a typed void for functional-style APIs

---

Philosophy

fabrik_result is built for clarity, simplicity, and real usage in domain-driven apps.
It provides only what you need, making it extremely lightweight.

---

Installation

dart pub add fabrik_result

---

Usage

Either

Use Either<Failure, Success> to safely model operations that may fail:

Either<Failure, User> result = await getUser();

result.fold(
  (failure) => handleError(failure),
  (user) => handleSuccess(user),
);

Unit

Use Unit when the success case doesn’t need to return data:

Either<Failure, Unit> result = await save();

result.fold(
  (failure) => showError(failure),
  (_) => showSuccessToast(),
);

Summary

• Lightweight alternative to dartz and other functional packages
• Built for simplicity and real-world Flutter/Dart apps
• Great for clean architecture and domain-driven design
