I'm trying to find the official Android Compose documentation, but I can't find it.
I'm looking for something like the Flutter docs.
What I need is to know the properties of the components and how to use them, something like the Flutter documentation.
The Jetpack Compose documentation can be found at https://developer.android.com/jetpack/compose
The documentation for all the classes is here and you can find a list of packages here.
Since you mention components and how to use them, the functions in the material library are probably most relevant to you. There's also a tutorial that demonstrates some basic usage.
