navigator error when i try to navigate from app bar icon click

'Navigator operation requested with a context that does not include a Navigator '

The context used to push or pop routes from the Navigator must be that of a widget that is a descendant of a Navigator widget'

kindly help

class MyGSt extends StatelessWidget

{

@override

Widget build(BuildContext context)

{

// void _gstnHistoryData()

//{

// Navigator.popAndPushNamed(context, "/GstnHistoryData");

// }

try

{

final appTitle = 'My GST Data';

return MaterialApp

(

title: appTitle,

home: Scaffold

(

appBar: AppBar

(

leading: new Image.asset('img/logo.png', fit: BoxFit.cover),

title: Text(appTitle),

actions: <Widget>

[

new IconButton

(

icon: new Icon(Icons.history),

onPressed: ()

{

Navigator.push(context,

new MaterialPageRoute(builder: (context) => new GstnHistoryData()));

},

),

],

),

body: MyData(),

),

routes: <String, WidgetBuilder>

{

"/GstnHistoryData": (BuildContext context) => new GstnHistoryData(),

}

);

}

catch(e)

Hi There,

Please can you change the code as follows:

Navigator.push(context,

new MaterialPageRoute(builder: (context) => new GstnHistoryData()));

to

Navigator.push(context,

new MaterialPageRoute(builder: (_) => new GstnHistoryData()));

Regards,

Mahi.
