Getting Started

1. Add library to your pubspec.yaml


dependencies:
  add_thumbnail: ^0.0.1

2. Import library in dart file

import 'package:add_thumbnail/add_thumbnail.dart';

3. How to use FilterList

Create of list of MediaInfo object

  List<MediaInfo> mediaList = [];

Create List of String

List<String> urlList = ["https://www.youtube.com/watch?v=uv54ec8Pg1k"];
   void openAddLinkDialog() async {
    // Open  thumbnail dialog to add link
    await Thumbnail.addLink(
      context: context,
      /// callback that return thumbnail information in `MediaInfo` object
       onLinkAdded: (mediaInfo) {
        if (mediaInfo != null && mediaInfo.thumbnailUrl.isNotEmpty) {
          setState(() {
            mediaList.add(mediaInfo);
          });
        }
      },
    );
  }

Create MediaList widget to show thumbnail list

Widget getMediaList() {
    return MediaListView(
      onPressed: (url) {
        print(url);
      },
      urls: urlList,
      mediaList: mediaList,
    );
  }

Call openAddLinkDialog function on floatingActionButton pressed

  
  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: Color(0xFFEEEEEE),
      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(
        onPressed: openAddLinkDialog,
        tooltip: 'Add link',
        child: Icon(Icons.add),
      ),
    );
  }
