The answer is `WillPopScope`. It will prevent the page from being popped by the system. You'll still be able to use `Navigator.of(context).pop()`
Checkout below code snippet.
@override Widget build(BuildContext context) { return new WillPopScope( onWillPop: () async => false, child: new Scaffold( appBar: new AppBar( title: new Text("data"), leading: new IconButton( icon: new Icon(Icons.ac_unit), onPressed: () => Navigator.of(context).pop(), ), ), ), ); }
