platformViewBackdrop property
Whether the pinned chrome floats over a native platform view.
The shell draws a hoisted cluster with its own GlassButton, and the
shader that button uses reads a captured backdrop the platform view is
never part of — so over a map or a video the capsule has nothing to
refract and renders inert, whatever buttonSettings asks for. Only a
live BackdropFilter samples the composited view, and this is what
routes the shell's copy there, exactly as GlassButton.platformViewBackdrop
does for the bar's own.
Implementation
final bool platformViewBackdrop;
