iOS

1. Create Share Extension

2. Replace yourios/Share Extension/Info.plist with the following:

<?xml version="1.0" encoding="UTF-8"?><!DOCTYPEplist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"><plistversion="1.0">  <dict>    <key>AppGroupId</key>    <string>$(CUSTOM_GROUP_ID)</string><key>CFBundleVersion</key><string>$(FLUTTER_BUILD_NUMBER)</string><key>NSExtension</key><dict><key>NSExtensionAttributes</key>        <dict>            <key>PHSupportedMediaTypes</key>               <array><!--TODO: Add this flag, if you want to support sharing video into your app-->                   <string>Video</string><!--TODO: Add this flag, if you want to support sharing images into your app-->                   <string>Image</string>               </array>            <key>NSExtensionActivationRule</key>            <dict><!--TODO: Add this flag, if you want to support sharing text into your app-->                <key>NSExtensionActivationSupportsText</key>                <true/><!--TODO: Add this tag, if you want to support sharing urls into your app-->            <key>NSExtensionActivationSupportsWebURLWithMaxCount</key>            <integer>1</integer><!--TODO: Add this flag, if you want to support sharing images into your app-->                <key>NSExtensionActivationSupportsImageWithMaxCount</key>                <integer>100</integer><!--TODO: Add this flag, if you want to support sharing video into your app-->                <key>NSExtensionActivationSupportsMovieWithMaxCount</key>                <integer>100</integer><!--TODO: Add this flag, if you want to support sharing other files into your app--><!--Change the integer to however many files you want to be able to share at a time--><key>NSExtensionActivationSupportsFileWithMaxCount</key><integer>1</integer>            </dict>        </dict><key>NSExtensionMainStoryboard</key><string>MainInterface</string><key>NSExtensionPointIdentifier</key><string>com.apple.share-services</string></dict>  </dict></plist>

3. Add the following to yourios/Runner/Info.plist:

...<key>AppGroupId</key><string>$(CUSTOM_GROUP_ID)</string><key>CFBundleURLTypes</key><array><dict><key>CFBundleTypeRole</key><string>Editor</string><key>CFBundleURLSchemes</key><array><string>ShareMedia-$(PRODUCT_BUNDLE_IDENTIFIER)</string></array></dict></array><key>NSPhotoLibraryUsageDescription</key><string>To upload photos, please allow permission to access your photo library.</string>...

4. Add the following to yourios/Runner/Runner.entitlements:

....<!--TODO:  Add this tag, if you want support opening urls into your app-->    <key>com.apple.developer.associated-domains</key>    <array>        <string>applinks:example.com</string>    </array>....

5. Add the following to yourios/Podfile:

...target'Runner'douse_frameworks!use_modular_headers!flutter_install_all_ios_podsFile.dirname(File.realpath(__FILE__))# Share Extension is name of Extension which you created which is in this case 'Share Extension'target'Share Extension'doinherit!:search_pathsendend...

6. Add Runner and Share Extension in the same group

7. Go to Build Phases of your Runner target and moveEmbed Foundation Extension to the top ofThin Binary.

8. Make yourShareViewControllerios/Share Extension/ShareViewController.swift inherit fromRSIShareViewController:

// If you get no such module 'receive_sharing_intent' error. // Go to Build Phases of your Runner target and// move `Embed Foundation Extension` to the top of `Thin Binary`.import receive_sharing_intentclassShareViewController:RSIShareViewController{          // Use this method to return false if you don't want to redirect to host app automatically.    // Default is trueoverridefunc shouldAutoRedirect()->Bool{returnfalse}}
