provideCheckNoChangesConfig

Used to disable exhaustive checks when verifying no expressions changed after they were checked.

This means that OnPush components that are not marked for check will not be checked. This behavior is the current default behavior in Angular. When running change detection on a view tree, views marked for check are refreshed and the flag to check it is removed. When Angular checks views a second time to ensure nothing has changed, OnPush components will no longer be marked and not be checked.

• interval will periodically run checkNoChanges on application views. This can be useful in zoneless applications to periodically ensure no changes have been made without notifying Angular that templates need to be refreshed.
• The exhaustive option will treat all application views as if they were ChangeDetectionStrategy.Default when verifying no expressions have changed. All views attached to ApplicationRef and all the descendants of those views will be checked for changes (excluding those subtrees which are detached via ChangeDetectorRef.detach()). This is useful because the check that runs after regular change detection does not work for components using ChangeDetectionStrategy.OnPush. This check is will surface any existing errors hidden by OnPush components.
