Getting Started

Add to your pubspec.yaml:

dependencies:
  qr_lens: ^1.0.0

Platform Setup

iOS: Add camera usage description to ios/Runner/Info.plist:

<key>NSCameraUsageDescription</key>
<string>Camera needed to scan QR codes</string>

Android: Ensure android/app/build.gradle has minSdkVersion 21 or higher.

Usage

import 'package:qr_lens/qr_lens.dart';

// Push ScannerPage as a full-screen route
Navigator.push(
  context,
  MaterialPageRoute(builder: (context) => const ScannerPage()),
);

The ScannerPage widget handles everything — camera initialization, scanning, overlay animations, and result display.

Customization

You can override the accent and success colors by importing scanner_theme.dart and changing kAccent and kSuccess in your own theme, or pass them via the widget constructors if you extend the classes.
