@override CacheDriver driver([ String? name ])

Implementation

@override
CacheDriver driver([String? name]) {
  if (name != null) {
    _validator.validateDriverName(name);
    final driver = _driverRegistry.getDriver(name);
    if (driver == null) {
      throw CacheException('Cache driver "$name" not registered');
    }
    return driver;
  }
  return _driverRegistry.getDefaultDriver();
}
