Add 180 degrees to isRotated logic

[Renato Marinho Gonçalves]

I'm using the package for a personal project and I notice this:

lib/src/controller line 417:

bool get isRotated => rotation == 90 || rotation == 270;

The right logict should be:

bool get isRotated => rotation == 90 || rotation == 270 || rotation == 180;
or
bool get isRotated => rotation != 0;

I've had issues with this as well!
