Thanks for writing such a beautiful App to explain Kotin flow. Could you please some resources to write the Android Test for Flow and Coroutines (for ViewModel and Repository layer).
Only solution I could find is Installing IntelliJ IDEA Community instead.
Open the project in that then I get an error about JDK configuration and click the Use settings JDK. The main.kt file is under src->main->kotlin and now the Play button works.
