isReferencedOutsideBuild property
Whether this provider is referenced outside of AppView.build().
This is true for anything that is change detected, has lifecycle hooks, matches a dynamically updated query, or is referenced in the template.
While the intent of this field is to generalize the concept, in reality
it's only ever false for TemplateRef when not queried or referenced.
Implementation
final bool isReferencedOutsideBuild;
