Android Jetpack Compose crashes when importing navigation compose

Question

i am trying to build an Android JetPack Compose app. My problem is that when i import the bottom navigation dependency in build.gradle:

def nav_compose_version = "1.0.0-alpha01"
implementation "androidx.navigation:navigation-compose:$nav_compose_version"

When i run the application, it crashes with the following error:

Answer 1

If you are using Compose 1.0.0-alpha07, you must use Navigation Compose 1.0.0-alpha02 as the internals of Compose have changed so much as to make alpha01 (which was built against Compose 1.0.0-alpha06) incompatible.
