uikit_bindings
This plugin allows you to use native UIKit components in your Flutter app using FFI.
Bindings are generated from UIKit Headers using ffigen.
This is experimental plugin and currently only limited number of components are supported.

Helper Functions
The library also provides several helper functions and extensions:

UIKitColorExtension.toUIColor() |

Regenerating bindings
This project uses Dart-API to use ffigen. To regenerate the bindings, run:
dart run tool/ffigen.dart
UIAction-based control callbacks require iOS 14 or later.
