The library you are suggesting have good amount of resources file. As extension doesn't support aar dependency, a developer may have to spend lot of time in modifying the library.
I think you can make same layouts you have shown in first post using already available extensions.
However, If you just need the extension with this dependency, you can hire an extension developer or place an amount you can pay. An extension developer may contact you.
Sometimes you do not need to use extensions. When I make apps that needs to be published to the gallery (i.e. no extensions allowed), I use Google Drawings to make backgrounds of cards, bars, etc. With the help of Google Drawings and arrangements, I’m all set. Find it out.
I want all the components of one ui but for now I will be happy with the appbar only see.
Also you will have to use the old library because new library is not yet ready.
