### Steps to reproduce

1. Run the sample app on iOS (either real device or simulator)
2. Choose any option of the three possibilities
3. Click on the "Press to open ..." button

### Expected results

A native, platform dependent file chooser should pop up.

### Actual results

Nothing - the action aborts with a `PlatformException`.

This applies to all three options available for iOS.
