Instalasi

1. Pastikan Flutter sudah terinstall di sistem Anda

2. Install dependencies:

   flutter pub get

3. Jalankan aplikasi:

   • Android (emulator/device):

     flutter run -d android

   • iOS (simulator/device, butuh macOS & Xcode):

     flutter run -d ios

   • Linux desktop:

     flutter run -d linux

   • Windows desktop:

     flutter run -d windows

   • macOS desktop:

     flutter run -d macos

   • Web (Chrome):

     flutter run -d chrome

   Jika project baru dibuat dari repo ini dan folder platform belum ada, jalankan flutter create . untuk mengenerate folder android, ios, linux, macos, windows, dan web.

Dependencies

• sqflite: ^2.3.0 - Database SQLite untuk Flutter
• path: ^1.8.3 - Utility untuk path manipulation
• intl: ^0.20.2 - Internationalization dan formatting
• shared_preferences: ^2.2.3 - Menyimpan hash PIN serta status terkunci
• crypto: ^3.0.3 - SHA-256 untuk hashing PIN
• sqflite_common_ffi: ^2.3.0 - Dukungan SQFLite di platform desktop
• sqflite_common_ffi_web: ^1.0.1+2 - Shim SQLite berbasis IndexedDB untuk Web
• cryptography: ^2.5.0 - PBKDF2 + AES-GCM untuk enkripsi data vault

Database Schema

Tabel passwords memiliki struktur:

• id: INTEGER PRIMARY KEY AUTOINCREMENT
• title: TEXT NOT NULL
• username: TEXT NOT NULL
• password: TEXT NOT NULL
• website: TEXT (nullable)
• notes: TEXT (nullable)
• created_at: TEXT NOT NULL
• updated_at: TEXT NOT NULL

Build & Deploy

Persiapan umum

• Pastikan dependencies terinstall:

  flutter pub get

• Jika target Web (Chrome), lakukan setup worker database sekali:

  dart run sqflite_common_ffi_web:setup

  Ini menyalin sqflite_sw.js dan sqlite3.wasm ke folder web/.

Android (APK)

1. Pastikan Android SDK siap (flutter doctor -v). Set ANDROID_SDK_ROOT/ANDROID_HOME bila diperlukan.
2. Build release:

   flutter build apk --release

3. Hasil APK:
   • build/app/outputs/flutter-apk/app-release.apk
4. Catatan:
   • Untuk rilis ke Play Store, lakukan penandatanganan (keystore + key.properties). Dokumentasi: flutter.dev → “Signing the app”.

Web (Static Hosting)

1. Pastikan setup web sudah dilakukan:

   flutter pub get
   dart run sqflite_common_ffi_web:setup

2. Build release:

   flutter build web --release

3. Hasil build ada di:
   • build/web/
4. Deploy ke static hosting apa pun (Nginx, Apache, GitHub Pages, Netlify, Vercel, dll.) dengan mengunggah isi folder build/web/.
5. Contoh serve lokal cepat:

   cd build/web
   python3 -m http.server 5000
   # buka http://localhost:5000

6. Catatan penting Web:
   • Data tersimpan di IndexedDB (melalui sqflite_common_ffi_web) dan terikat ke origin (domain+port). Gunakan domain/port tetap agar data tidak “hilang”.
   • Saat development, jalankan dengan port tetap:

     flutter run -d chrome --web-port 5000 --web-hostname localhost

   • Setelah setup sqflite_common_ffi_web, pastikan file sqflite_sw.js dan sqlite3.wasm tersedia di folder web/.
