      context: context,
      /// callback that return thumbnail information in `MediaInfo` object

          setState(() {
            mediaList.add(mediaInfo);
          });
        }
      },
    );
  }

      appBar: AppBar(
        title: Text(widget.title),
      ),
      body:(mediaList == null || mediaList.isEmpty) && (urlList == null || urlList.isEmpty)
          ? Center(
              child: Text(
                "Press add button to add thumbnail.",
                style: TextStyle(color: Colors.black54, fontSize: 16),
              ),
            )
          : getMediaList(),
      floatingActionButton: FloatingActionButton(
