I'm working on an application which requires me to perform a left-to-right slide animation with the "current" widget being the source and the destination which gets animated to.
The animation should provide an affect like an iOS native slide to go back animation.
How can this be achieved?
This is the official tutorial for Page Transitions.
Check the link below, it has the perfect example you are looking for:
Slide Animation between Screens
I hope it helps.

I have an app that I have created using Flutter. It is simple and just loads a list of slides from Firebase and displays that list in a slideshow format using the carousel_slider package. It works great but I would like an animation to be done when the user slides to the next slide. I know that sounds vague, but for a better description, I wanted an animation like what happens in Google Primer.
In this picture the animation is pretty well visible
In Primer, the slide flies down in a stylish manner and does the same but upwards if you slide up, instead of going straight back
Hello all I am building Tinder like swipe in Flutter. So far so good I have made the stack of cards together with the gesture detector when the user swipes left/right. However my issue come when I try to animate on click of a button. Under the stack of cards there are 2 buttons which you can like or dislike on button click. I would like to get an advice how I can approach the animation when the user clicks on either button. Below is my code for displaying the stack. Best wishes
There are several options to animate the card off screen. Since you're already using a Stack, AnimatedPosition is probably the best option.
You could also use Transform.translate to set the transform property of an AnimatedContainer. Or, if you want more control over the animation you could use a SlideTransition.
For a good overview of how to decide which animations you need, see this video from two days ago: https://www.youtube.com/watch?v=GXIJJkq_H8g
There's also https://pub.dev/packages/animations for more pre-packed options.
When you swipe vertically, image is dragged towards the swipe, with fading out animation of black background.
And after release, it smoothly returns to it's previous position on the screen, like Hero animation does.
How is it possible to recreate such an effect using Flutter? The same scenario, in fullscreen photo view.
photo_view package is desired for fullscreen, so it shouldn't interfere with zooming.
What you need is actually an out-of-the-box widget, and it's surprisingly easy to use. It's called Hero. Basically, you wrap the widget you want to animate like that in a Hero widget, with a specific tag string, and, when you navigate to another screen, you wrap the destination widget in another Hero with the same tag. An effect like the one you shared can be achieved by wrapping two widgets with the same photo with Heroes in different PageRoutes.
Check out this Flutter widget of the week video to get you started, and this Flutter.dev article for a more detailed explanation on Hero widgets.
Edit: I see you are looking for a more specific image-viewer behavior. Then, I suggest you use the photo_view package, which includes many functionalities to visualize images, including the hero transition with swipe-dow-to-dismiss behaviors, pinching to zoom, etc.
I found the solution.
To create such an animation, you should use extended_image package, which has SlideOutPage widget for creation of such transitions.
I want to know to the best way in order to develop a widget/view which can work as instagram, snapchat stories which illustrated in image below. There are many depndencies for android, but can't find any for flutter.
I'm thinking to use carousal/viewpager to move between stories of different users, but I'm unable to get how to move backward and forward in between stories of single user(either image or video) with progress bar on top of it which will move automatically to next when progress bar completes.
Try to create a custom ViewPager perhaps using Stack + Transform and use GestureDetector to switch between pages/stories.
I know this question has been asked for a long time, but for those who still ask the same question, you can use this library: https://pub.dev/packages/story_view or look at it's source to implement the same thing.
Not sure if you also want to give the user a chance to manually switch to the next image.
Here are some basic ingredients you want to use for an animated "story":
AnimationController with duration depending on the number of images in the story. Start the animation to go through the images and to animate the progress bar. The animation controller usually has a range from 0.0 to 1.0. Let's say you have 5 images. You would display the first image from 0.0 to 0.2, the second image from 0.2 to 0.4...
AnimatedBuilder that listens to the animation controller. The content inside the animation builder will be rebuilt every frame while the animation runs. Inside of the builder, calculate which image must be shown.
CustomPaint to manually draw a progress bar with sections for the single image. Pass the current animation value and the number of images to your CustomPainter.
Image widget to draw the image.
in xcode just doing the transition. set of image in the nsarray,like slide show. have to change the image using transition for right to left using touch
I think you have to describe your question briefly.You can use Page control for that.It may be more useful to you.
You can get sample code in below link "http://developer.apple.com/library/ios/#samplecode/PageControl/Introduction/Intro.html"
use the leftswiping gestures and right swiping gestures.
