PageTransitionsTheme class
Defines the page transition animations used by MaterialPageRoute for different TargetPlatforms.
The MaterialPageRoute.buildTransitions method looks up the
current PageTransitionsTheme with Theme.of(context).pageTransitionsTheme
and delegates to buildTransitions.
If a builder with a matching platform is not found, then the ZoomPageTransitionsBuilder is used.
This example shows a MaterialApp that defines a custom PageTransitionsTheme.
