deleteRouteDependency static method

void deleteRouteDependency(String key)

Schedules a dependency to be deleted when the route finishes disposing.

The registration might have been superseded by a new one during disposal. This method safely peels the stale factory out of the memory without affecting the active one.

Implementation

static void deleteRouteDependency(String key) {
  final dep = GetInstanceExt.factories[key];
  if (dep == null) {
    Get.log('Instance "$key" already removed.', isError: true);
    return;
  }

  final live = dep.dependency;
  final hasSubscribers =
      live is ListNotifierSingleMixin &&
      !live.isDisposed &&
      live.hasSubscribers;
  if (dep.lateRemove != null || !hasSubscribers) {
    Get.delete(key: key);
    return;
  }

  WidgetsBinding.instance.addPostFrameCallback((_) {
    final current = GetInstanceExt.factories[key];
    if (current == null) return;
    if (!identical(current, dep)) {
      // The registration was superseded meanwhile
      var chain = current.lateRemove;
      while (chain != null) {
        if (identical(chain, dep)) {
          Get.delete(key: key);
          return;
        }
        chain = chain.lateRemove;
      }
      return;
    }
    if (!live.isDisposed && live.hasSubscribers) {
      dep.isDirty = false;
      Get.log(
        'Instance "$key" was kept alive on route disposal: '
        'widgets are still subscribed to it.',
      );
      return;
    }
    Get.delete(key: key);
  });
}
