deleteAll method

void deleteAll({ bool force = false, })

Deletes the dependency registered under key on behalf of a disposed route, keeping it alive when still-mounted widgets depend on it.

Meant for internal usage of GetDependencyScope: when a scope is disposed, the instances linked to it are deleted. An instance that still has widget subscribers (GetBuilder/GetX listeners) at that moment may be shared with widgets of another, still-visible route — e.g. a controller created during a rebuild of a lower route's subtree while the disposed route was topmost — so its deletion is deferred to the end of the frame, after the disposed route's own subtree has unmounted and released its subscriptions:

• if no subscriber remains, the instance is deleted normally;
• if subscribers remain, they belong to still-mounted widgets of other routes and the instance is kept alive (it is disposed later by its creator widget's unmount or an explicit delete).

A registration superseded while the route was disposing (pending lateRemove chain) is peeled synchronously, exactly like delete. Deletes all registered instances from memory, invokes their onDelete/close lifecycles, and cleans up resources.

• force If true, deletes even the instances marked as permanent.
