When using .pngs as icons for the MaterialAboutActionItem Builder, they show as black boxes in version 3.1.2
cardBuilder.addItem(MaterialAboutActionItem.Builder()
.text("Test")
.icon(R.drawable.test)
.build())
Although this works perfectly in 2.4.2 with the same code, the icons are rendered properly.
The style is a child of "Theme.MaterialComponents.Light.DarkActionBar".
Thanks for this great library, just a little confusing why the newest version doesn't show .png, which is the preferred Android format for drawables. https://developer.android.com/guide/topics/graphics/drawables
