Is your feature request related to a problem? Please describe. Yes, there is a huge gap between what's shown on the material design guidelines of what's possible and beautiful examples, vs what's shown here (which can be complicated yet still not the same): https://m2.material.io/components?platform=android https://github.com/material-components/material-components-android/tree/master/catalog

Describe the solution you'd like For each screenshot and animation on the website, actually show how you did it, meaning have a link on the official website to the sample/file to reach, so that each time we see something nice, we could reach it and learn from it, how it's recommended to use it. What's the point in demonstrating things of a library, yet not showing the source of how you did it... I'm sure the same thing is true for the other platforms and frameworks too.

Describe alternatives you've considered Some things can be done easily, and I personally prefer minimal examples first, but here we didn't get minimal ones AND what's shown on the official website.

Additional context Example is of Bottom sheet: https://m2.material.io/components/sheets-bottom#behavior

Compare this bottom sheet which has a FAB at the top, and gets disappeared when expanding, taking full screen: Bottom sheets full screen.zip

With this sample we have: scrcpy_2024-08-03_12-37-39.zip
