Piyé carane struktur proyèk Flutter?

Question

Accepted Answer

Proyèk Flutter nduwé struktur standar — nganggo direktori kanggo kode Dart, kode khusus platform, aset, lan konfigurasi. Mangerteni struktur lan file-file penting (utamané `pubspec.yaml` lan `lib/`) kuwajib kanggo navigasi lan membangun aplikasi Flutter.

## Direktori lan file kunci

```text
my_app/
  lib/                  → your DART CODE lives here (the heart of the app)
    main.dart           → the ENTRY POINT (the main() function; app starts here)
  pubspec.yaml          → project config: DEPENDENCIES, assets, metadata (very important)
  android/              → Android-specific native project/config
  ios/                  → iOS-specific native project/config
  web/ windows/ etc.    → other platform folders
  test/                 → tests
  assets/               → images, fonts, etc. (declared in pubspec.yaml)
```

## pubspec.yaml — file konfigurasi kunci

```yaml
name: my_app
dependencies:
  flutter:
    sdk: flutter
  http: ^1.0.0           # add packages here (from pub.dev)
  provider: ^6.0.0
flutter:
  assets:
    - assets/images/     # declare assets to bundle
```

`pubspec.yaml` ngumumake **dependencies** (paket saka pub.dev), aset, lan metadata — sampeyan mbukak `flutter pub get` kanggo nginstal dependencies.

## main.dart — titik masuk

```dart
import 'package:flutter/material.dart';

void main() => runApp(MyApp());      // runApp starts the Flutter app with a root widget

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(home: HomeScreen());   // the app's root widget
  }
}
```

## Ngorganisir lib/ nalika aplikasi berkembang

```text
→ Beyond main.dart, organize lib/ into folders (by feature or layer):
  lib/screens/, lib/widgets/, lib/models/, lib/services/, lib/providers/ (common)
→ Keep code organized as the app grows (separation of concerns).
```

## Napa iku penting

Mangerteni carane struktur proyèk Flutter diatur adalah pengetahuan praktis yang perlu untuk navigasi, membangun, lan ngorganisir aplikasi Flutter, dadi iku pengetahuan dasar sing berguna.

Mangerteni **direktori lan file kunci** — yen **`lib/` nyekel kode Dart sampeyan** (inti aplikasi, ngendi sampeyan mbuwang paling akeh wektu), **`main.dart` yaiku titik masuk** (ngendi aplikasi wiwit via `main()` lan `runApp`), folder **platform** (`android/`, `ios/`, etc kanggo kode native khusus platform), direktori `test/` lan `assets/` — kuwajib kanggo nemokake dalan sampeyan ngubengi proyèk Flutter.

Mangerteni **`pubspec.yaml`** utamané penting: iku file konfigurasi kunci ngumumake **dependencies** (paket saka pub.dev, ekosistem paket Flutter), aset, lan metadata — sampeyan bakal nyunting iku terus-terusan kanggo nambah paket (mbukak `flutter pub get` kanggo nginstal), dadi iku pusat pengembangan Flutter.

Mangerteni **main.dart lan titik masuk** (piyé `main()` lan `runApp` wiwit aplikasi nganggo widget akar) netalesake carane aplikasi Flutter wiwit.

Mangerteni carane **ngorganisir `lib/` nalika aplikasi berkembang** (menyang folder dening fitur utawa lapisan — screens, widgets, models, services — kanggo separasi masalah) nggambarake praktik apik kanggo proyèk sing bisa dirawat.

Amarga kerja nganggo Flutter mbutuhaké navigasi struktur proyèk, ngatur dependencies via pubspec.yaml, mangerteni titik masuk, lan ngorganisir kode, lan amarga pengetahuan iki kuwajib dasar praktis kanggo pembangunan Flutter apa wae, mangerteni carane struktur proyèk Flutter diatur — direktori kunci, pubspec.yaml, titik masuk, lan organisasi kode — yaiku pengetahuan dasar praktis sing berharga kanggo kerja nganggo proyèk Flutter, kuwajib kanggo membangun lan ngrawat aplikasi lan kompetensi dhasar kanggo pengembangan Flutter.
