Sadly Android developers don't share the same experience.
It was required lots of vocal complaints for them to start having any kind of Material Design support on Android libraries.
True, also there are many items in the Google Design Guidelines that don't have any code example of how to implement them in real life.
material-ui.com is not an official library by Google.
It makes such a difference to be able to see the output and then quickly look at the source code. Really wonderful development experience.
