delete<S> method

Future<bool> delete<S>({ String? tag, bool force = false, })

Removes a dependency from the scope.

If the dependency is currently instantiated and implements LevitScopeDisposable, its LevitScopeDisposable.onClose method will be called.

Set force to true to delete dependencies marked as permanent.

Returns true if the dependency was found and deleted.

    final info = _registry[canonicalKey];
    _removeAlias(key);
    if (info != null) {
      _notifyDelete(keyString, info, 'deleteAlias');
    }
    return true;
  }

  final info = _registry[key];
  if (info == null) return false;

  if (info.permanent && !force) return false;

  _notifyDelete(keyString, info, 'delete');
  _removeCanonicalBinding(key);
