delete<T extends Object?> method

bool delete<T extends Object?>([ String? id, Object? ref ])

Deletes the instance from _instancesByKey but keep the _builder function.

Returns true when the instance has been deleted.

Implementation

bool delete<T extends Object?>([String? id, Object? ref]) {
  final instanceKey = ReactterInstance.generateKey<T?>(id);
  var reactterInstance = _instancesByKey[instanceKey];

  if (reactterInstance == null || reactterInstance.instance == null) {
    reactterInstance = ReactterInstance<T>(id);
    Reactter.log(
      'Instance "$reactterInstance" already deleted.',
      isError: true,
    );
    return false;
  }

  if (ref != null) {
    reactterInstance.refs.remove(ref.hashCode);
  }

  if (reactterInstance.refs.isNotEmpty) {
    return false;
  }

  _removeInstance<T>(reactterInstance);

  Reactter.dispose(reactterInstance);

  return true;
}
