See original GitHub issue

Kotlin code: Screenshot 2020-05-29 at 12 04 18

Workaround is to just use a Kotlin lambda: Screenshot 2020-05-29 at 12 17 28

But adding Slider.LabelFormatter breaks it again: Screenshot 2020-05-29 at 12 19 06

Expected behavior: No compile errors

Material Library version: 1.2.0-beta01

Thanks for the details @Thomas-Vos it does seem this is an issue with Kotlin, I filled this if you want to follow the resolution:

https://youtrack.jetbrains.com/issue/KT-39265

We’ll address the label formatter though

Great to hear it will be fixed soon!

For the listener issue, I am using Android Studio 4.0 stable and Kotlin 1.3.72. Furthermore I have the new Kotlin type inference enabled (-XXLanguage:+NewInference). It appears that if I remove the option to enable the new inference, all works fine. So it could be a bug in Kotlin instead. Here is a sample project with the new type inference enabled, which reproduces the issue. Android Studio should show the error in MainActivity.
