IllegalStateException when my state contains androidx.compose.ui.graphics.Color #735
Description
My app crashes when the state contains an object from androidx.compose.ui.graphics.Color. It's kind of a pain because I need to store it as a string and then build a Color object with it when I need it.
I'm curious what it is about this class that it doesn't like so that I can avoid certain classes in the future. Here is the stack trace. The exception doesn't mention anything about the Color class, but if I replace this with a String, everything works fine.
stacktrace:
