By “flying” after all going backwards and forwards bouncing from board sides. And also as it’s been mentioned previously in “Different methods for producing animation in PowerApps” part move is really a defined improvement in time. And you can find 2 methods for attaining that: flirt4free-app declarative-alike and imperative-alike. For now don’t bother that, I’ll explain it later on, the most important thing now could be that we’ll focus on imperative-alike means.
