I am trying to create a fade transition for pushing routes, for that created a custom route like
class CustomPageRoute<T> extends MaterialPageRoute<T> {
CustomPageRoute({WidgetBuilder builder, RouteSettings settings})
: super(builder: builder, settings: settings);
@override
Widget buildTransitions(BuildContext context, Animation<double> animation,
Animation<double> secondaryAnimation, Widget child) {
return FadeTransition(opacity:animation, child: child, );
}
}
And calling it from a button press like
onPressed: () {
Navigator.push(context, CustomPageRoute(builder: (context) {
return FirstScreen();
}));
}
But this give a weird animation with sliding + fade. How to avoid the sliding animation in this?
Here is the output of my code:
You should extend from PageRoute
instead of MaterialPageRoute
class CustomPageRoute<T> extends PageRoute<T> {
CustomPageRoute(this.child);
@override
// TODO: implement barrierColor
Color get barrierColor => Colors.black;
@override
String get barrierLabel => null;
final Widget child;
@override
Widget buildPage(BuildContext context, Animation<double> animation,
Animation<double> secondaryAnimation) {
return FadeTransition(
opacity: animation,
child: child,
);
}
@override
bool get maintainState => true;
@override
Duration get transitionDuration => Duration(milliseconds: 500);
}
Usage:
final page = YourNewPage();
Navigator.of(context).push(CustomPageRoute(page));
