Flutter swift plugin creating and showing an arbitrary UIViewController

Question

I'd like to show a swift UIViewController in a flutter app. So far, I successfully :

• wrote a 'programmatic' UIViewController
• used another full swift iOS app to test that I could self.present this view
• wrote a flutter plugin, and I tested that I can exchange data fine between this plugin and my flutter app.

Now, inside this plugin, I can instantiate my CustomViewController, but I have no way to show it on screen, because I'm writing a FlutterPlugin, and it obviously doesn't have any of the facilities like self.window, self.present, etc. How can I do that ?

Answer 1

You can get the current rootController from the keyWindow and present your custom view controller from there.

UIApplication.shared.keyWindow?.rootViewController?.present(...
