🔐 Platform Permissions Setup

Since this SDK accesses the local device camera and photo library, you must declare these permissions in your host application:

iOS (ios/Runner/Info.plist)

Add the following entries inside your <dict> tag:

<key>NSCameraUsageDescription</key>
<string>This app requires access to the camera to take photos for your Virtual Try-On.</string>
<key>NSPhotoLibraryUsageDescription</key>
<string>This app requires access to the photo library to pick photos for your Virtual Try-On.</string>

Android (android/app/src/main/AndroidManifest.xml)

Add the following permissions:

<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
