I'm going to implement some nice animation to sliver appbar's bottom property. So that when i pressed on the button, it should show up like fadeinDown animation. and at the next time should disappear with fadeOutUp animation.
As you can see now it is appearing and disappearing suddenly. which is not good user experience.
Could someone help me with it? I'm having trouble to give animation to PreferedSizeWidget(appBar)
You can fix this with TweenAnimationBuilder.

In my case, need up and down swipe button in flutter. My UI design should exactly match the attached screen shot. Can anyone help me to achieve this please??
So I am working working on something in unity (2d game). I have a list of button (UI) on my scene and I want to implement a scrolling mechanism. What is the best way to go about it? Currently , I can scroll through horizontally because I have added a "scroll rect" to the the canvas holding the buttons as I start the game. However when I try to scroll back (horizontally, it goes beyond the Buttons. Is there a way to make the scrolling continuous such that as I scroll, from the first UI element when I get to the last one and I keep scrolling, it continues with the first element. or what should I do. please let me Know If i should clarify.
In the Scroll rect you can set the movement type. I don't think the kind of "infinite scroll" you are asking for is available.
For your case, I think that the Use Elastic or Clamped mode to force the content to remain within the bounds of the Scroll Rect should do the work.
In the case of the infinite scroll specifically needed, you would need to ask for that explicitely and show your attempt for more specific help.
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.
I have a screen in Corona to display a puzzle, and once user guess the correct answer, I'm going to display a simple pop up on the screen to do the congratulation a long with close button to dismiss the popup, now I need for a simple work around to disable any control or behaviour on the original screen while displaying the popup, how can I do that?
I think you need to do this by stop or pause transitions, timers and animations etc. before you go to scene with pop up.
You can add transparent rectangle from transparent image file (not just rectangle, as it will not be touchable).
Size of this rectangle must be the size of all screen.
Position of rectangle - under your popup (or better make it as part of your popup).
Add listeners to this rectangle on touch and tap that will just return false - so it will prevent any clicks under it.
That will save you from pausing / disabling buttons, that you don't want to disable/pause.
so I have an app and I have a sliding drawer on the left that can be pulled out/revealed by a button tap or a gesture. It looks like this.
I wanted to animate the drawer so it had a folding animation kind of similar to this.
I have looked around the internet extensively and didn't find anything.
Does anyone know whether this is possible? Thanks.
The following article describes the folding animation using CATransfromLayer. I think this might help.
