This is an Jetpack Compose example project. I'm collecting a bunch of sample codes for Widgets/Composables https://developer.android.com/jetpack/compose. You can find the samples i got from the Google AndroidX git here

Please be aware that Compose is still experimental and should not be used in a production application.
