error in flutter the url_launcher is not working

I'm trying to use url_launcher so that I can view articles by URL but I get a MissingPluginException. Can someone help me? Here's some of my code:

Widget _builder(Article article){
  return new Padding(
    padding: const EdgeInsets.all(8.0),
    child: ListTile(
      title: new Text(article.text,style: TextStyle(
       fontSize: 24.0,
      ),
    ),
    subtitle: new Text(article.by),
    onTap: () async {
      final fakeUrl='www.${article.domain}';
      if (await canLaunch(fakeUrl)){
        launch(fakeUrl);
      } else print("could not be opened");
    ),
  );
}

Here's my error:
