GlassGroupScope class Composition

Carries the group down to the surfaces inside it.

An InheritedWidget holding an object whose identity never changes, so it never notifies: geometry moves every frame and must not rebuild anybody's subtree, which is the same rule GlassScope follows.

Put in the tree by GlassGroup and GlassUnion; the nearest one wins.

Constructors

GlassGroupScope({required GlassBlendGroup group, required Widget child, Key? key})
