Export all Classes (thundernail_slider.dart, video_view.dart, ...) and enable to disable cropping in trim_slider

Hello,

Again great job.

I am trying to create my own app and need recreate my own app based on these bricks.

• It would be great to get access to all classes
• It would be great to activate/deactivate Cropping and eventually the position slider in the slider.

Thanks !
