Flutter widgets ที่วาด QR พร้อมเพย์ (Thai PromptPay / EMVCo) จากเบอร์มือถือ / เลขบัตรประชาชน-ภาษี / e-Wallet พร้อมจำนวนเงิน

Flutter widgets that render a Thai PromptPay (EMVCo) QR code from a mobile number, National ID / Tax ID or e-Wallet, with an optional amount.

This is the Flutter rendering layer on top of the pure-Dart thai_promptpay codec (kept pure-Dart so it still runs back-end / CLI). This package adds the widgets — it depends on flutter + qr_flutter + thai_promptpay

• thainum (for the baht text), and re-exports the codec, so importing this package alone gives you encodePromptPay / decodePromptPay / PromptPayTarget etc. too.

PromptPayQr — the QR widget

import 'package:thai_promptpay_flutter/thai_promptpay_flutter.dart';

// Convenience constructors (accept 0812345678, 081-234-5678, +66…):
PromptPayQr.mobile('0812345678', amountSatang: 10000); // 100.00 baht
PromptPayQr.nationalId('1101700230708');
PromptPayQr.eWallet('004999000000001', size: 180);

// Or pass a target directly:
PromptPayQr(
  target: const PromptPayTarget(PromptPayType.mobile, '0812345678'),
  amountSatang: 5000,
  size: 240,
);

Money is in integer satang (1 baht = 100 satang) — exact, no double. If the number/ID is invalid the widget shows errorBuilder (a default placeholder when null) instead of throwing:

PromptPayQr.mobile(
  userInput,
  errorBuilder: (context, error) => const Text('Invalid PromptPay number'),
);

PromptPayQrCard — a drop-in card

A Material card with the QR, a title, the recipient, and the amount shown as Thai baht text (via thainum):

PromptPayQrCard(
  target: const PromptPayTarget(PromptPayType.mobile, '0812345678'),
  amountSatang: 10000,            // shows '฿100.00' + 'หนึ่งร้อยบาทถ้วน'
  title: 'พร้อมเพย์ / PromptPay',
  recipientLabel: 'ร้านกาแฟ',
);

Notes

• Output is verified through the codec — thai_promptpay is checked byte-for-byte against the canonical PromptPay references.
• Scope: personal PromptPay (mobile / National ID / e-Wallet). Bill-Payment is not included yet.
