.
List _items;
double _fontSize = 14;

@override void initState(){ super.initState(); // if you store data on a local database (sqflite), then you could do something like this Model().getItems().then((items){ _items = items; }); }

@override Widget build(BuildContext context) { return Tags( key:_tagStateKey, textField: TagsTextField( textStyle: TextStyle(fontSize: _fontSize), constraintSuggestion: true, suggestions: [], //width: double.infinity, padding: EdgeInsets.symmetric(horizontal: 10), onSubmitted: (String str) { // Add item to the data source. setState(() { // required _items.add(str); }); }, ), itemCount: _items.length, // required itemBuilder: (int index){
final item = _items[index];

        return ItemTags(
              // Each ItemTags must contain a Key. Keys allow Flutter to
              // uniquely identify widgets.
              key: Key(index.toString()),
              index: index, // required
              title: item.title,

              removeButton: ItemTagsRemoveButton(
                onRemoved: (){
                    // Remove the item from the data source.
                    setState(() {
                        // required
                        _items.removeAt(index);

              ), // OR null,
              onPressed: (item) => print(item),
              onLongPressed: (item) => print(item),
        );

  },
);    

}

final GlobalKey _tagStateKey = GlobalKey(); // Allows you to get a list of all the ItemTags _getAllItem(){ List lst = _tagStateKey.currentState?.getAllItem; if(lst!=null) lst.where((a) => a.active==true).forEach( ( a) => print(a.title));
}
