## 1. Apa tiga lapisan utama Clean Architecture dalam aplikasi Flutter?

**Jawaban**

Clean Architecture membagi aplikasi menjadi tiga lapisan yang berbeda: Domain (entity dan use case), Data (repository dan data source), dan Presentation (UI dan state management). Pemisahan ini memastikan logika bisnis tetap independen dari detail implementasi seperti framework UI atau database. Lapisan Domain tidak memiliki ketergantungan pada lapisan lain, yang memudahkan pengujian dan pemeliharaan.

## 2. Apa peran utama lapisan Domain dalam Clean Architecture?

**Jawaban**

Lapisan Domain berisi logika bisnis murni dari aplikasi, termasuk entity (objek bisnis) dan use case. Lapisan ini sepenuhnya independen dari framework, database, dan UI. Lapisan ini mendefinisikan aturan bisnis dan kontrak (interface) yang harus diimplementasikan oleh lapisan lain, sehingga memastikan inti aplikasi tetap stabil terhadap perubahan teknis.

## 3. Mengapa Repository pattern penting dalam arsitektur Flutter yang terstruktur dengan baik?

**Jawaban**

Repository pattern bertindak sebagai abstraksi antara logika bisnis dan sumber data. Pattern ini memungkinkan lapisan Domain mengakses data tanpa mengetahui asalnya (API, cache lokal, database). Abstraksi ini memudahkan penggantian sumber data, pengujian unit dengan mock, dan pengelolaan strategi caching yang kompleks sambil menjaga kode bisnis tetap bersih.
