So easy is it now to implement a next field behavior for forms, meaning that the focus is moved as soon the user tabs the next button on the keyboard

nextField.dart

class _MyHomePageState extends State<MyHomePage>
    with SingleTickerProviderStateMixin {

  TabController _tabController;

  FocusScopeNode _node = FocusScopeNode();   /// <-----------------

  @override
  void initState() {
    _tabController = TabController(length: 3, vsync: this);
    super.initState();
  }

  @override
  Widget build(BuildContext context) {
    //   return TestWidget();
    return Scaffold(
      resizeToAvoidBottomPadding: true,
      appBar: new AppBar(
        backgroundColor: Colors.white,
        centerTitle: true,
        title: new Text("Create Event"),
      ),
      body: new Center(
        child: FocusScope(   /// <-------------
          node: _node,       /// <-------------
          child: Column(
            children: <Widget>[
              Expanded(
                child: SingleChildScrollView(
                  child: Container(
                    padding:
                        EdgeInsets.symmetric(horizontal: 30.0, vertical: 20.0),
                    child: Column(
                      crossAxisAlignment: CrossAxisAlignment.stretch,
                      children: [
                        TextFormField(
                          onFieldSubmitted: (_) => _node.nextFocus(), //<------------
                          textInputAction: TextInputAction.next,
                        ),
                        TextFormField(
                          onFieldSubmitted: (_) => _node.nextFocus(), //<------------
                          textInputAction: TextInputAction.next,
                        ),
                        TextFormField(
                          onFieldSubmitted: (_) => _node.nextFocus(), //<-----------
                          textInputAction: TextInputAction.next,
                        ),
                        // Expanded(child: Container(color: Colors.blue,)),
                      ],
                    ),
                  ),
                ),
              ),
              Padding(
                padding: const EdgeInsets.all(8.0),
                child: TabBar(
                  labelColor: Theme.of(context).accentColor,
                  controller: _tabController,
                  tabs: [
                    Tab(
                      text: "General",
                    ),
                    Tab(
                      text: "Location & Time",
                    ),
                    Tab(
                      text: "Requirements",
                    ),
                  ],
                ),
              )
            ],
          ),
        ),
      ),
    );
  }
