platformViewBackdrop property
Forces the BackdropFilter fallback render path so premium glass renders cleanly over an iOS PlatformView.
The premium shader pipeline cannot sample PlatformView pixels (e.g.
a Mapbox MapWidget), so over one it would render the group as a
solid slab. When true, the group falls back to Flutter's
BackdropFilter — which can sample PlatformViews on Impeller — so
quality: GlassQuality.premium can be used over a PlatformView
without the slab artifact. Forwarded to the underlying
GlassButton.custom (items mode) / GlassContainer (children mode).
Defaults to false.
Implementation
final bool platformViewBackdrop;
