Widget orientation/direction/rotation property?

[DaMilyutin]

Hi,
I couldn't find anything on this topic so...
Is it possible to rotate Widget (with discrete of 90 degrees)?

Now I'm playing with plotter example and I'd like to move Pitch slider and text to the left of rendered image which to be rotated by 90 degrees and add Yaw slider at bottom of image.
What I want is Text and Slider to be rotated.

Can I implement it with current state of art in sixtyfps?

What I've found in Qt is

upd: for Flutter there are some functionalities, too

RotatedBox is closest functionality in Flutter for my question.
