MacosToolbarPassthroughScope class

An optional "scope" for toolbar items.

When a scoped item detects a change that would normally trigger a reevaluation of their position and size, they instead notify their parent scope, which then notifies all their scoped items to reevaluate and update their positions and sizes.

Since Flutter is optimized to avoid unnecessarily drawing UI elements, detecting some changes in UI can be expensive or cumbersome. Even worse, sometimes the implementation may not be able to detect these changes at all (such as in some scrolling widgets or widgets that either move or change size in uncommon ways), resulting in flutter widgets being out of sync relative to their native counterpart.

Wrapping multiple MacosToolbarPassthrough under a MacosToolbarPassthroughScope allows you to both: 1- Trigger a reevaluation on all scoped items when any of them internally requests a reevaluation. 2- Manually trigger these reevaluation events if needed (see: notifyChangesOf).
