Mobile Technology Stack

Flutter 3.x

Flutter 3.x

Flutter was chosen for the mobile application because:

  • Single codebase for iOS and Android
  • High-performance native compilation
  • Rich widget library for consistent UI
  • Excellent camera and QR scanning support
  • Hot reload for rapid development
  • Strong type safety with Dart

Key Packages

Package Purpose Version
flutter_riverpod State management ^2.4
go_router Declarative routing ^13.0
mobile_scanner QR code scanning ^4.0
dio HTTP client ^5.4
flutter_secure_storage Secure data storage ^9.0

State Management: Riverpod

Riverpod 2.4+

Riverpod was selected over alternatives (Provider, Bloc, GetX) because:

  • Compile-time safety for dependency injection
  • No BuildContext required for state access
  • Excellent testing support with overrides
  • Automatic disposal of resources
  • Async state handling with AsyncValue

QR Code Technology

QR Code Generation

simple-qrcode 4.2+

The SimpleQRCode library was chosen for server-side generation:

  • Support for all error correction levels (L, M, Q, H)
  • SVG and PNG output formats
  • Logo embedding with automatic masking
  • Color customization
  • Laravel facade integration

Error Correction Levels

Level Recovery Use Case
L (Low) 7% Clean environment, high data density
M (Medium) 15% Standard usage (default)
Q (Quartile) 25% Logo embedding
H (High) 30% Heavy logo embedding, harsh conditions

QR Code Scanning

mobile_scanner 4.0+

The mobile_scanner package provides:

  • ML Kit barcode scanning on Android
  • AVFoundation on iOS for optimal performance
  • Support for all common barcode formats
  • Camera preview widget integration
  • Torch/flash control
  • Front/back camera switching

GS1 Standards Implementation

GS1 Digital Link Standard

Reference

Implementation follows the GS1 Digital Link Quick Start Guide (2024).

URL Structure

https://[domain]/[primary-key]/[secondary-keys]?[data-attributes]

Example:
https://qr2.ignited.cloud/01/09506000134352/10/ABC123/21/XYZ789?17=251231&3103=000500

GTIN Validation

QR Igniter implements full GTIN validation including:

  • Length validation: GTIN-8, GTIN-12, GTIN-13, GTIN-14
  • Check digit calculation: Modulo 10 algorithm
  • GCP extraction: Company prefix identification
  • Country code parsing: GS1 prefix to country mapping
// GTIN Validation Service
class GtinValidator
{
    public function validate(string $gtin): bool
    {
        // Normalize to 14 digits
        $gtin14 = str_pad($gtin, 14, '0', STR_PAD_LEFT);

        // Calculate check digit
        $sum = 0;
        for ($i = 0; $i < 13; $i++) {
            $multiplier = ($i % 2 === 0) ? 3 : 1;
            $sum += (int)$gtin14[$i] * $multiplier;
        }

        $checkDigit = (10 - ($sum % 10)) % 10;
        return $checkDigit === (int)$gtin14[13];
