🧪 Full Flutter Example

import 'dart:io';

import 'package:flutter/material.dart';
import 'package:flutter/services.dart';
import 'package:camerapack/camerapack.dart';

void main() {
  runApp(const MyApp());
}

class MyApp extends StatefulWidget {
  const MyApp({super.key});

  @override
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  String? imagePath;
  final _camerapack = Camerapack();

  Future<void> _capturePhoto() async {
    try {
      final path = await _camerapack.captureImage(isfront: true);
      if (mounted && path != null) {
        setState(() {
          imagePath = path;
        });
      }
    } on PlatformException catch (e) {
      debugPrint('Failed to capture image: $e');
    }
  }

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      debugShowCheckedModeBanner: false,
      home: Scaffold(
        body: Center(
          child: Padding(
            padding: const EdgeInsets.all(24.0),
            child: Column(
              mainAxisAlignment: MainAxisAlignment.center,
              children: [
                TextButton(
                  onPressed: _capturePhoto,
                  child: const Text('Click Photo'),
                ),
                const SizedBox(height: 20),
                if (imagePath != null)
                  Image.file(
                    File(imagePath!),
                    width: 200,
                    height: 200,
                    fit: BoxFit.cover,
                  )
              ],
            ),
          ),
        ),
      ),
    );
  }
}

This will:

• Launch the native camera screen (front camera)
• Capture a photo
• Return the file path
• Display the captured image in the app

📂 iOS Configuration

To access the camera and photo library on iOS, add the following permissions to your ios/Runner/Info.plist:

<key>NSCameraUsageDescription</key>
<string>We need camera access to take photos</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>We need access to your photo library</string>

💡 These keys provide user-facing explanations for why your app needs access. Make sure the descriptions match your app’s functionality.
