Add pictures to show how the widget looks in the README.md file

[HazardCodeBolt]

I have seen about this dependency in pub.dev, but in the main page there is no image that illustrates how will the widget look after it is used. I think it is better for you to include an image or a GIF that shows the different ways to use this widget.

Hi @HazardCodeBolt,

Thank you for using my package.

I added the screenshots in previous versions.
But unfortunately, githubusercontent domain is not working, so I have decided to remove it.
I will add the screenshots in the next update.
Alternatively, you can visit the demo web app for illustration.

Thanks

Well,
Your package carousels are well designed and smooth, and that is what I liked about it.
I found out that there is a demo in the documentation after you said it. I was a little in a hurry just to decide what package to use.
Thank you for the response.
