Friends App Android Client Ep12 - TDD on Android Screencast
In this episode, we are working on making the signup screen look nice and polished. We introduce some animation which seems to be quite easy with Jetpack Compose. We made a nice improvement by decoupling the screen state from the actual composable into a standalone class.
