IOS "Add To Siri" button in Flutter with a Platform View

In case you'll ever need to implement the "add to Siri" button in #flutter then here is an example solution with an explanation. This solution uses Platform views, so this video can also saver as an introduction to them. Potentially, other solutions are also possible (i.e. with PlaformChannels). In case you have a different approach, share it in the comments. Either way, we have to write some of #ios #swift or Objective-C.
There's yet no plugin for this, so feel free to create one in case you have time for maintaining plugins! :D

Please note, I'm not an iOS dev and so, although, the swift code you see here will work if you plan to use it as is, there are some issues as I learned at a PR. First, the constraints are reversed. Secondly, in case you need to access the actual frame size, then you can get it in the `layoutSubviews()` method. However, I"m not accessing the frame, and therefore this method is not necessary and the constraints can be set up at `init`. Finally, the method that gets a `RootViewController` is way overcomplicated. You can just directly get the root controller in one line and all that code with atabBarController` is not necessary. Well, that was a piece of code I copied from somewhere. :D Good luck!

Thank you for this tutorial. How to perform certain action on shortut's run? I've tried by trying to get information about incoming userActivity but it didn't work. func application(_ application: UIApplication, continue userActivity: NSUserActivity, restorationHandler: @escaping ([Any]?) -> Void) -> Bool {
