Card Scan Flutter Plugin

Flutter plugin for scanning credit/debit cards directly in your app.
Supports Android (Google Pay OCR API) and iOS (native SwiftUI scanner).

🚀 Features

• Scan card number with camera
• Recognize expiration date
• Capture cardholder name (iOS only)

⚙️ Setup

Android

• Connect Google Pay API for test or production
• Ensure Google account signed in on device

iOS

• Minimum iOS version: 13.0
• Add camera permission in Info.plist:

<key>NSCameraUsageDescription</key>
<string>We need camera access to scan your card</string>

🔥 Usage

import 'dart:io';
import 'package:card_scan/card_scan.dart';

// Android usage example
if (Platform.isAndroid) {
  final result = await GoogleCardScanner.scan(testEnvironment: true);
  print(result?.number);
}

// iOS camera view example
Stack(
  children: [
    /// Camera + scanner
    Positioned.fill(
      child: CardScan(
        onScanned: (event) {
          if (!isProcessed) {
            isProcessed = true;
            Navigator.of(context).pop(event); // return event
          }
        },
      ),
    ),

    // Custom overlay here
  ],
)

• GoogleCardScanner.scan() — Android OCR using Google Pay
• CardScannerModal — iOS SwiftUI camera view

🧪 Notes

• Android OCR requires a signed-in Google account and production access to Google Pay API.
• Use testEnvironment: true for test cards.
• iOS scanning works offline.
