Usage

Create DirectSelectList and fill it with items using itemBuilder

    final dsl = DirectSelectList<String>(
        values: _cities,
        defaultItemIndex: 3,
        itemBuilder: (String value) => getDropDownMenuItem(value),
        focusedItemDecoration: _getDslDecoration(),
        onItemSelectedListener: (item, index, context) {
          Scaffold.of(context).showSnackBar(SnackBar(content: Text(item)));
        });

Create items like this

  DirectSelectItem<String> getDropDownMenuItem(String value) {
    return DirectSelectItem<String>(
        itemHeight: 56,
        value: value,
        itemBuilder: (context, value) {
          return Text(value);
        });
  }

Create decorations for focused items

  _getDslDecoration() {
   return BoxDecoration(
     border: BorderDirectional(
       bottom: BorderSide(width: 1, color: Colors.black12),
       top: BorderSide(width: 1, color: Colors.black12),
     ),
   );
 }

Create DirectSelectContainer and fill it with your data

Scaffold(
      appBar: appBar,
      body: DirectSelectContainer(
        child: Padding(
          padding: const EdgeInsets.all(16.0),
          child: Column(
            mainAxisSize: MainAxisSize.min,
            verticalDirection: VerticalDirection.down,
            children: <Widget>[
              SizedBox(height: 150.0),
              Padding(
                padding: const EdgeInsets.all(8.0),
                child: Column(
                  children: <Widget>[
                    Container(
                      alignment: AlignmentDirectional.centerStart,
                      margin: EdgeInsets.only(left: 4),
                      child: Text("City"),
                    ),
                    Padding(
                      padding: const EdgeInsets.fromLTRB(0, 8, 0, 0),
                      child: Card(
                        child: Row(
                          mainAxisSize: MainAxisSize.max,
                          children: <Widget>[
                            Expanded(
                                child: Padding(
                                    child: DirectSelectList<String>(
                                                     values: _cities,
                                                     defaultItemIndex: 3,
                                                     itemBuilder: (String value) => getDropDownMenuItem(value),
                                                     focusedItemDecoration: _getDslDecoration(),
                                                     onItemSelectedListener: (item, index, context) {
