How to create a Webview with bottom navigation opened from a listview item?

[l-k22]

I hope someone can help me or point me in the right direction. I have a screen with a tabbedview, on the 3rd tab I have my ebook's content list. When the user clicks a chapter I would like to open a webview to display the html content. However, I require a bottom navigation so that the user can navigate the ebook (the options being, view the content list, bookmark the current page, previous page and next page buttons).
This is an example of my code

return new ListView.builder(
       scrollDirection: Axis.vertical,
         padding:
              new EdgeInsets.fromLTRB(15.0, 0.0, 15.0, 0.0),
         itemCount: chapterList.length + 1,
         itemBuilder: (context, int index) {
              return new FlatButton(
                    onPressed: () =>
                                    flutterWebviewPlugin.launch(chapterList[index].href),
                       child: new Container(
                        width: width,
                        padding: const EdgeInsets.symmetric(vertical: 10.0),
                          child: new Padding(
                            padding: indentAmount(chapterList[index]),
                               child: new Text(
                                 '${chapterList[index].title}',
                                  textAlign: TextAlign.left,
                                   ),
                               ),
                     ));
              });

Row bottomNav(CustomChapterObj chapter) {
    return Row(
        mainAxisSize: MainAxisSize.max,
        mainAxisAlignment: MainAxisAlignment.spaceBetween,
        children: <Widget>[
          IconButton(
              icon: Icon(Icons.home, color: Constants.Orange),
              onPressed: () {}),
          IconButton(
              icon: Icon(Icons.view_headline, color: Constants.Orange), //show the content list widget
              onPressed: () {}),
          IconButton(
              icon: Icon(Icons.arrow_back, color: Constants.Orange),
              onPressed: () {}),
          IconButton(
              icon: Icon(Icons.arrow_forward, color: Constants.Orange),
              onPressed: () {}),
          IconButton(
              icon: Icon(Icons.bookmark_border, color: Constants.Orange),
              onPressed: () {}),
        ]);
  }

Many thanks for the great package!
