I have simple Flutter app with list of items that are loaded from Firebase database (Cloud Firestore). As you can see - there is button for adding items and each item can be deleted or edited. When I press edit button for selected item, AlertDialog with TextField appears, in this TextField user can see current item name and edit it. I have problems only with dismissing dialog after editing. new IconButton( icon: new Icon(Icons.edit, color: Colors.white), onPressed: (){ showItemUpdateDialog(context, document); } ) ....... void showItemUpdateDialog(BuildContext context, DocumentSnapshot item) { String itemName = ""; var textContoller = new TextEditingController(); textContoller.text = item['name']; var dialog = new AlertDialog( title: new Text("item name"), content: new TextField( controller: textContoller, onChanged: (value) {newName = value;}, ), actions: <Widget>[ new FlatButton( ...

This is how I want to acces the filed in the Snapshots.
