Prevent Dialog from Hardware back button

[prasantco]

I am passing this value(false) to the barrierDismissible but its functionality is not working properly.We want to prevent/stop the dismissable of dialog from external hardware back button. YYDialog YYNoticeDialog() { return YYDialog().build() ..width = 120 ..height = 110 ..backgroundColor = Colors.black.withOpacity(0.8) ..barrierDismissible = false ..borderRadius = 10.0 ..showCallBack = () { print("showCallBack invoke"); } ..dismissCallBack = () { print("dismissCallBack invoke"); } ..widget(Padding( padding: EdgeInsets.only(top: 21), child: Image.asset( 'images/success.png', width: 38, height: 38, ), )) ..widget(Padding( padding: EdgeInsets.only(top: 10), child: Text( "Success", style: TextStyle( fontSize: 15, color: Colors.white, ), ), )) ..animatedFunc = (child, animation) { return ScaleTransition( child: child, scale: Tween(begin: 0.0, end: 1.0).animate(animation), ); } ..show(); }

you can add WillPopScope like this: ..widget( WillPopScope( onWillPop: () { return Future.value(false); }, child: your widget ) )
