PredictiveBackPageTransitionsBuilder class
Used by PageTransitionsTheme to define a MaterialPageRoute page transition animation that looks like the default page transition used on Android U and above when using predictive back.
Predictive back is only supported on Android U and above, and if this PageTransitionsBuilder is used by any other platform, it will fall back to FadeForwardsPageTransitionsBuilder.
When used on Android U and above, animates along with the back gesture to reveal the destination route. Can be canceled by dragging back towards the edge of the screen.
