None of the above solutions don't work for me.

Flutter suggests this - Put your widget inside new GestureDetector() on which tap will hide keyboard and onTap use FocusScope.of(context).requestFocus(new FocusNode())

class Home extends StatelessWidget {
@override
  Widget build(BuildContext context) {
    var widget = new MaterialApp(
        home: new Scaffold(
            body: new Container(
                height:500.0,
                child: new GestureDetector(
                    onTap: () {
                        FocusScope.of(context).requestFocus(new FocusNode());
                    },
                    child: new Container(
                        color: Colors.white,
                        child:  new Column(
                            mainAxisAlignment:  MainAxisAlignment.center,
                            crossAxisAlignment: CrossAxisAlignment.center,

                            children: [
                                new TextField( ),
                                new Text("Test"),                                
                            ],
                        )
                    )
                )
            )
        ),
    );

    return widget;
}}
