WhScreenFlow

A non fragment approach

to use Screenflow, your Activity need to inherit from ScreenflowActivity:

class MainActivity : ScreenFlowActivity() {

	override fun getLayoutId(): Int = R.layout.screenflow

	override fun provideContentFrameForScreenFlow(): FrameLayout = screenflow_content

	override fun getInitialScreenClass(): Class<out Screen> = GithubJobSearchScreen::class.java

	override fun setDataForInitialScreen(screen: Screen) {

	}

	override fun exit() {
		finish()
	}
} 

inherit from Screen to simply manage your state variables

class ScreenA(screenFlow: ScreenFlow) : Screen(...) {

  //foo must be either primitive type or implement parcelable or serializable
  var foo by state(null)

  var lazyFoo by lazyState{ Foo() }

  var lateInitFoo by lateInitState<Foo>()

  //do things with foo
