use WillPopScope widget like this

return new WillPopScope(
    onWillPop: () async {
   //  your logic here 
   //  
   return Future.value(false); // true if you want the back button to take effect 
},
    child: new Scaffold(
     //then the rest of your code...

This answer is outdated. you can use either popscope() or override dispose() functions.
