@override
void replaceInstance<T>(T instance, {String? key}) {

    final data = (key == null) ? layersGraph.getBindByClassName(this, className: className) : layersGraph.getBindByKey(this, bindKey: key);

    final injector = data!.key;

    final index = (key == null) ? injector.binds.indexWhere((bind) => bind.className == className) : injector.binds.indexWhere((bind) => bind.key == key);
