Swipe List Item for more options (Flutter)

I created a package for doing this kind of layout: flutter_slidable (Thanks Rémi Rousselet for the based idea)

With this package it’s easier to create contextual actions for a list item. For example if you want to create the kind of animation you described:

You will use this code:

new Slidable(
  delegate: new SlidableDrawerDelegate(),
  actionExtentRatio: 0.25,
  child: new Container(
    color: Colors.white,
    child: new ListTile(
      leading: new CircleAvatar(
        backgroundColor: Colors.indigoAccent,
        child: new Text('$3'),
        foregroundColor: Colors.white,
      ),
      title: new Text('Tile n°$3'),
      subtitle: new Text('SlidableDrawerDelegate'),
    ),
  ),
  actions: <Widget>[
    new IconSlideAction(
      caption: 'Archive',
      color: Colors.blue,
      icon: Icons.archive,
      onTap: () => _showSnackBar('Archive'),
    ),
    new IconSlideAction(
      caption: 'Share',
      color: Colors.indigo,
      icon: Icons.share,
      onTap: () => _showSnackBar('Share'),
    ),
  ],
  secondaryActions: <Widget>[
    new IconSlideAction(
      caption: 'More',
      color: Colors.black45,
      icon: Icons.more_horiz,
      onTap: () => _showSnackBar('More'),
    ),
    new IconSlideAction(
      caption: 'Delete',
      color: Colors.red,
      icon: Icons.delete,
      onTap: () => _showSnackBar('Delete'),
    ),
  ],
);
