I am making a carousel with cross fade animation which I am using AnimatedSwitcher with FadeTransition to achieve such effect. The effect is fine but I want the carousel to be swipeable. I had tried PageView but I do not want the slide animation. Does anyone have any solution to this? Please Help. Thanks in advance.
The custom carousel I currently use.
AnimatedSwitcher(
duration: const Duration(milliseconds: 500),
transitionBuilder: (Widget child, Animation<double> animation) {
return FadeTransition(child: child, opacity: animation);
},
child: Image.asset(
imageList[currentIndex.toInt()],
key: ValueKey<int>(currentIndex),
),
If you do not want slide animation, do not use PageView.
Stick with your current implementation with AnimationSwitcher. If you want to add gesture support, wrap it with GestureDetector and listen on the onHorizontalDrag... or onVerticalDrag... events.

Flutter. There are two screens. On the first screen, there is one widget in the center (a container with text). On the second screen (ListView), the same (container with text), but shifted to the side, and another one is added(TextField). How do I animate the transition between these screens? Move the first widget (container) I know how. But how do I add a TextField at the same time ? ......as an option, I thought to apply the opacity of the TextField , but this place on the first screen is already occupied. Probably a complete replacement of the screens is needed here.
Here you have example of quick animation. This code should be in onpressed
Navigator.push(
context,
PageRouteBuilder(
transitionsBuilder: (BuildContext context,
Animation<double> animation,
Animation<double> secAnimation,
Widget child) {
animation = CurvedAnimation(
parent: animation,
curve: Curves.fastLinearToSlowEaseIn);
return ScaleTransition(
scale: animation,
child: child,
alignment: Alignment.center,
);
},
transitionDuration:
const Duration(milliseconds: 300),
pageBuilder: (BuildContext context,
Animation<double> animation,
Animation<double> secAnimation) {
return **urpage**();
}));
I want to make a custom transition like PageView in flutter when navigate to another page like image below but I do not know how. I used SlideTransitiondid but it does not give me the desired result
import 'package:flutter/material.dart';
import 'package:get/get.dart';
class SlideTransitions extends CustomTransition {
#override
Widget buildTransition(
BuildContext context,
Curve curve,
Alignment alignment,
Animation<double> animation,
Animation<double> secondaryAnimation,
Widget child) {
return Align(
alignment: Alignment.center,
child: SlideTransition(
position: Tween(begin: Offset(1.0, 0.0), end: Offset(0.0, 0.0))
.animate(animation),
child: child,
),
);
}
}
pageview transition image
you can use page_transition PageTransitionType.rightToLeft . It's kinda similar to pageview swipe
the effect I want to achieve is that the user scrolls sideways when the user uses the gesture to scroll down. Something like on this page.
ListView does not work with gestures - but it does work with a mouse, but that doesn't solve the problem when the user is using gestures, e.g. on a laptop.
Does anyone have an idea how to handle it?
I did not find any dedicated functionality in some widget, but here is my workaround:
final scrollController = ScrollController();
Listener(
onPointerSignal: (pointerSignal) {
if (pointerSignal is PointerScrollEvent) {
scrollController.animateTo(
scrollController.offset + pointerSignal.scrollDelta.dy,
curve: Curves.decelerate,
duration: const Duration(milliseconds: 200),
);
}
},
child: SingleChildScrollView( // or any other
controller: scrollController,
child: ...,
),
)
I am trying to implement shared_axis_transition on my flutter application's bottom navigation. The setup consists of A root page with bottom navigation bar and 4 other pages which changes according to the index of bottom navigation. The problem is, each of the widgets are stateful and have their own initstate. When I try to apply animation, after animation completes, the widget rebuilds itself and sort of flickering effect is seen. How do I solve the issue? My code pattern is as follow:
RootWidget{
body: PageTransitionSwitcher(
duration: const Duration(milliseconds: 300),
transitionBuilder: (
Widget child,
Animation<double> animation,
Animation<double> secondaryAnimation,
) {
return SharedAxisTransition(
child: child,
animation: animation,
secondaryAnimation: secondaryAnimation,
transitionType: _transitionType,
);
},
child: [First(),Second(),Third(),Fourth()].elementAt[index],
),
),
bottomNavigationBar(),
}
Each of the widget have their own initstate which I believe is causing this.
p.s For the first time since I started flutter, animations in debug environment looks smoother than animation in release...
I have a widget that is displaying data, which changes over time, i'd like for that old data to fade out, then fade in new data when its available (passed in by the parent).
How can i achieve this?
I think this might help u:
AnimatedOpacity(
opacity: _visible ? 1.0 : 0.0,
duration: Duration(milliseconds: 500),
child: Text('Hello World!),
);
