    What does this: 
    Caused by: java.lang.IllegalStateException: Composition requires an active composition context
    mean? What are the possible causes?

    based on the some quick search seems like the composition context is for to contain the Slot Table and it it referenced as a 
    root
    . My assumption based on that is you are calling a compose function without a root to be able to attach itself.

    if you comment out the 
    SetContent
    function in your activity you can achieve the same result:
    //setContent {
        epicContent()
//}

    It sounds like you're calling a composable function outside of a composable function - it's like suspend, they can only be called from other composables

    Trying to debug it, I have a breakpoint inside every 
    @Composable
    function I have, it crashed before even reaching any breakpoints 😒

    Found out what was the problem 🙂
    Copy to Clipboard
    Was using some composable functions (
    +state
    ) to assign values to 
    val
    , outside of a 
    @composable
    function

    Can we actually fail the compilation process if a compose function is called in a none compose function? something like:
    fun a() {
  val a = +state{}
}

    Not only in function though

    You could declare them as I did in a class

    @kioba That is the plan. We plan make effects 
    @Composable
    functions that return values. When that is done they will be reported as errors just as trying to call an 
    @Composable
    outside and 
    @Composable
    is an error.
