# HashChangeEvent constructor Null safety

HashChangeEvent(

1. String type,
2. {bool canBubble: true,
3. bool cancelable: true,
4. String? oldUrl,
5. String? newUrl}

)

## Implementation

    factory HashChangeEvent(String type,
        {bool canBubble: true,
        bool cancelable: true,
        String? oldUrl,
        String? newUrl}) {
      var options = {
        'canBubble': canBubble,
        'cancelable': cancelable,
        'oldURL': oldUrl,
        'newURL': newUrl,
      };
      return JS('HashChangeEvent', 'new HashChangeEvent(#, #)', type,
          convertDartToNative_Dictionary(options));
    }
