在本章中，指导你的 AI 代理将装饰过的照片保存到你的手机上，并可选择让它也在浏览器中工作。

在本章中，你将添加最后一个核心功能：将照片、贴纸等保存到手机的相册中。

🌐 In this chapter, you'll add the final core feature: saving the photo, sticker and all, to your phone's photo library.

Add a "Save" option to the row of options, with a download icon. When I tap it, capture just the photo with the sticker on it (not the whole screen) using the react-native-view-shot library, and save the result to my phone's photo library using the expo-media-library library. Ask for permission the first time if needed, and show an alert confirming that the image was saved.

Make the Save option also work when the app runs in a web browser. The react-native-view-shot library doesn't support the web, so when the platform is web, use the dom-to-image library to capture the image and download it as a file instead.

如果结果与你预期的不符，请告诉代理你看到的情况。当出现异常情况部分有操作指南。
