split_button_m3e: Alignment of menu is not correct and always aligns to the left of the screen.

[stonemaster]

Thanks for this very interesting package first of all!

I checked out the example and for some reason the popup menu is not aligned to the trailing chevron. The screenshot is taken from running the example on Linux, but I have first seen that problem in the app running on ANdroid I wanted to integrate this button.

I can reproduce that with all buttons in the example.

I am using Flutter 3.38.7
