noteChange method

void noteChange()

Declares a change nothing above the content is painted for.

The last resort under GlassContentDeclaration.declared: the host observes a scroll, its own repaint and the composited layers on its own. What is left is a change none of those can see.

Reach it with GlassProxyScope.maybeOf(context)?.noteChange().

Free under GlassContentDeclaration.undeclared, where the proxy is re-recorded anyway, and the difference between a working screen and a frozen one under the default.

Implementation

void noteChange() => _changes.notify();
