There should be something broke in Material theme, till dev 6 I did not noticed anything weird, but now when I change the theme of the app at runtime very strange things happen, for example I have a list display function that only works well (in the theming sense ) if I surround it by a surface(shape=Rectangle), either if I skip the surface or the shape, the list goes drawn without the changed theme. And there are more quirks and oddities all of them hard to predict or imagine.

what

Surface

is doing: drawing the background on the

surface

color from the

ColorPalette

and changes the default text color for the subtree to

onSurface

from the

ColorPalette

. what other unexpected changes do you see?

Fwiw this might be related to the bug around ambients in default expressions being broken. This will hopefully be fixed in dev11
