Animation of the closing drawer on navigate


Hi all,

I have made a very simple app with drawer and navigation, and I get a quirk while closing drawer on navigate (and page change) on iOS: the drawer disappears before the animation is complete.
I enabled slow animation in the emulator and the effect is shown in the attached GIF below (for push animation, but the same happens with default drawerTransition).
The navigate() is triggered on button tap inside the drawer.

Is it due to the animation curve? (And in this case can I access and change the default animation curve?) Or is it a bug?

Thank you very much,
