I migrated to Android Studio 3.5, and found a very strange bug in Code Analysis - in runs in a cycle on my Splitties DSL files because of internal crashes. I tried to localize the problem, and found that the root cause is in AppCompat split. It fails on the following declaration:

private val appCompatStyles = AppCompatStyles(ctx)
    private val buttons = appCompatStyles.button

    val button = buttons.default {
    }

while the following replacement works well:

val button = view<AppCompatButton>(::AppCompatButton){
            }

Do you have the same issue if you don't put

appCompatStyles.button

in a property and use it only when creating a button?

@louiscad, yes, the problem is still there if I move styles to method:

val appCompatStyles = AppCompatStyles(ctx)
            val buttons = appCompatStyles.button
            val crashingButton = buttons.default { }

It's weird. I don't use

AppCompatStyles

nowadays since I moved to

MaterialComponentsStyles

, but they are very similar and it works fine for me on AS 3.5.0 and Kotlin 1.3.50. I'm using the latest dev version of Splitties though, compiled with 1.3.41.

I just tested with Material styles:

val materialStyles = MaterialComponentsStyles(ctx)
            val buttons =  materialStyles.button
            val crashingButton = buttons.outlined { }

The problem is the same. I guess we should wait for JetBrains answer.
