afollestad/material-dialogs ? reverse-engineered prompt

Build me an Android library in Kotlin that makes it really easy to create beautiful Material style dialogs, with a simple core dialog API and a few add on modules for common things like text input, file picking, color picking, date and time pickers, bottom sheets, and lifecycle aware dialogs.

I want the dialogs to feel polished and fluid, work nicely with modern Android and AndroidX, and be easy to customize without a lot of boilerplate. Please include a small sample app that shows the main dialog types in action, so I can see how to use them right away.

Keep it split up in a clean way so the core piece works on its own, and the extra features are separate pieces I can add only when I need them. If you need current Android or Kotlin docs for best practices, look them up online first.
