⚡ Integration in 1 Minute

1. Add Dependency

Add this to your Flutter project's pubspec.yaml:

dependencies:
  snapit_sdk:
    path: ../virtual-tryon-sdk-flutter # Or use git/pub dependency

2. Launch the Try-On Flow

Import the package and call SnapIT.launchTryOnFlow with a single line of code:

import 'package:snapit_sdk/snapit_sdk.dart';

void openVirtualTryOn(BuildContext context) {
  SnapIT.launchTryOnFlow(
    context: context,
    apiKey: "YOUR_SMD_API_KEY",              // smd_live_...
    userId: "DEVELOPER_USER_ID",             // From your SMD console dashboard
    garmentImageUrl: "https://yourstore.com/images/shirt_102.jpg",
    productId: "sku_shirt_102_blue",         // Optional SKU tracking
    externalUserId: "consumer_myntra_77102",  // Optional customer tracking
    metadata: {                              // Optional custom payload
      "campaign": "summer_fest_2026",
      "gender": "male"
    },
    theme: SnapITTheme(
      primaryColor: const Color(0xFFFF3F6C), // Custom brand color (e.g. Myntra pink)
      fontFamily: 'Outfit',
    ),
    onSuccess: (resultImageUrl, generationId) {
      print("Try-On Completed! Result: $resultImageUrl");
      // Handle success (e.g., save preview link or show congratulations)
    },
    onFailure: (errorMessage) {
      print("Try-On Failed: $errorMessage");
    },
  );
}

🔐 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" />
