DialogFragment with slide animations. Since the animation is applied again if Activity resumes again after showing this dialog, here there's a workaround to remove enter animation after it already happened once

DialogFragment+slideAnimation.kt

...
import androidx.fragment.app.DialogFragment
import android.os.Handler
...
class MyDialogFragment : DialogFragment() {
    ...
    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        setupSlideFromTopAnimation()
        
        // workaround to fix slide animation repeating when activity resumes
        dialog?.setOnShowListener { Handler().post { setupSlideToTopAnimation() } }
    }
    ...
}

DialogFragmentExtensions.kt

val DialogFragment.window: Window? get() = dialog?.window

fun DialogFragment.setupSlideFromTopAnimation() {
    window?.setWindowAnimations(R.style.SlideFromTopAnimation)
}

fun DialogFragment.setupSlideToTopAnimation() {
    window?.setWindowAnimations(R.style.SlideToTopAnimation)
}
