Printer App

Printer App — bu Flutter yordamida yaratilgan dastur bo‘lib, u Bluetooth termal printerlar bilan ishlash uchun mo‘ljallangan. Ushbu ilova ESC/POS printerlari orqali matn, barkod va rasmlar chop etish imkoniyatini beradi.

📦 Ishlatilgan paketlar

Paket	Versiya	Tavsif
print_bluetooth_thermal	^1.1.0	Bluetooth termal printer bilan ishlash
permission_handler	^11.3.1	Ruxsat so‘rash va boshqarish
esc_pos_utils_plus	^2.0.3	ESC/POS kodlari yaratish
image	^4.2.0	Rasmlarni qayta ishlash

📲 O‘rnatish

Dastur kodini klonlash va pub get ishlatish:

git clone https://github.com/USERNAME/printer_app.git
cd printer_app
flutter pub get

🚀 Foydalanish

1. Bluetooth printerni ulang
2. Ilovada printerni qidirib, ulang
3. Matn, barkod yoki rasm chop eting

🛠 Xususiyatlar

✅ Bluetooth orqali ulanish ✅ ESC/POS printer qo‘llab-quvvatlash ✅ Matn, barkod va rasmlar chop etish ✅ Android va iOS qo‘llab-quvvatlash

📜 Ruxsatlar

Dastur quyidagi ruxsatlardan foydalanadi:

• Bluetooth ulanishi → Printerga ulanadi
• Fayl o‘qish/yozish → Rasmlarni yuklash

AndroidManifest.xml fayliga quyidagilarni qo‘shing:

<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
<uses-permission android:name="android.permission.BLUETOOTH_CONNECT" />

📷 Rasm chop etish misoli

import 'package:print_bluetooth_thermal/print_bluetooth_thermal.dart';
import 'package:esc_pos_utils_plus/esc_pos_utils.dart';
...
  static Future<List<int>> printImage(String assetPath) async {
    List<int> bytes = [];
    final profile = await CapabilityProfile.load();
    final generator = Generator(PaperSize.mm80, profile);
    bytes += generator.reset();

    final ByteData data = await rootBundle.load(assetPath);
    final Uint8List bytesImg = data.buffer.asUint8List();
    final image = decodeImage(bytesImg);
    bytes += generator.image(image!);

    return bytes;
  }

...

📌 Muammolar

Agar permission denied xatosi chiqsa, permission_handler sozlamalarini tekshiring va ruxsatlarni qo‘shing.
