positionedToastBuilder

fluttertoast has a positionedToastBuilder parameter, allowing to place a toast anywhere on the screen with Positioned.

It solves the problem when a toast is hidden behind the system keyboard:

There's no such a builder in this package, but only StyledToastPosition (which is equal to Gravity and knows nothing about MediaQuery and thus, the system keyboard).
