title: Creating A Share Button Using Flutter for iOS and Android?
body: <p>I'm converting some older Swift apps with Flutter.  How can I create a "share" button using flutter that at least gets Facebook and Twitter and make it cross platform for my iOS and Android versions.  Here is the Swift code I use....</p>
  
  <pre><code>let activityViewController : UIActivityViewController = UIActivityViewController(
              activityItems: [firstActivityItem, secondActivityItem, image], applicationActivities: nil)
  
          // This lines is for the popover you need to show in iPad
          activityViewController.popoverPresentationController?.sourceView = (self.shareBTN)
  
          // This line remove the arrow of the popover to show in iPad
          activityViewController.popoverPresentationController?.permittedArrowDirections = UIPopoverArrowDirection()
          activityViewController.popoverPresentationController?.sourceRect = CGRect(x: 150, y: 150, width: 0, height: 0)
          actInd.stopAnimating()
          self.present(activityViewController, animated: true, completion: nil)
  </code></pre>
