I'm looking for trajectory animation just like how https://leo9studio.com/ has done. You see while scrolling, those balls get scrolled from top to bottom. How can we replicate exactly in Flutter Web?
Additionally, how to create such a smooth scrolling effect in Flutter?
rive.app would be a good place to start looking, since you aren't really providing any context or code other than just a random idea, they have a great community and I have used their packaged for some neat animation on my web apps. They have a way to create your own designs and animations which would probably be the case there, unless you wanted to make it all with code then that would be a different story.
Or look at this post here How to animate a path in flutter?

I have a gif demonstrating electrical-like animation
The full gif is here: https://pin.it/3RGDs7W
Anyone knows how can implement this kind of animation on Flutter or I have to have a sequence of images to animate it
The most feasible method is to use this gif in Stack below the button. Creating an animation like this is very difficult and also it will decrease the screen FPS and consume more resource. The other way I can think of is creating this animation on rive.app but this will also take a very long time and you will have to learn how to create animations on rive.
I know there are game/sprite engines written for Flutter, but my goal is to better understand painting and widgets, so I want to do this myself.
If I wanted a bunch of small widgets that could move around on a gameboard, what would be the best way to do this? Would I just create a box widget with fixed dimensions and have a bunch of children where I could control their position?
One example would be having a playing area with scrabble tiles that could be moved around. Or Tetris blocks falling. Different widgets that can be anywhere and that can be moved. I'm just looking for someone to point me in the right direction. Thanks.
You can draw custom shapes and lines using canvas in flutter and then animate them as flutter supports 60 frames per second. You need to understand customPaint very well. Here is a great demonstration of how to use customPaint to draw custom shapes.

I am creating an application in Swift, and I would like to make an introduction screen that shows off my logo. I want the logo to slam down on the screen, which will then cause a crack, and then that crack slowly grows. I think I can figure out slamming the logo down (by shrinking a UIView of my logo to a certain point), but I am having trouble deciding how to create the crack that will form from slapping down. Do I use views? I am lost.
This is the closest thing that I found to what I would like to do. Sadly, I do not have this software.

I have created a similar effect before. And to achieve the crack a created multiple images of a growing crack and created an array of images for that screen crack. All you have to do then is animate the images if the imageView.
The other way you can Handel this is to actually draw the crack your self by code which is not difficult really, because in reality it’s just lines and then animate them. But in my experience just using the first method gives a much nicer effect because the images you use can have tons of effects using PS or equivalent.
I would suggest to go with third party like lottie. In lottie files there some animation you except there, you can also message the designer to help out animation. Its very simple to use in swift.

Lottie animation are done in aftereffects using bodymoving extension and exported as json file to use in xcode.
I want to make an endless vertical scrolling layer that gives the impression that the main character is moving upwards. I have been brainstorming on how to achieve this.
My issue is that I want objects to appear as if they are coming from above and below the screen at the same time. Secondly, I want to be able to move the main character to create and destroy box2d joints between it and some of the objects appearing on the screen. What is the best way to achieve this with consuming too much memory? I would appreciate any help on this.
Apple did a wonderful tutorial of this in a WWDC 2011 video session. It was "UITableView Changes, Tips & Tricks" and it's about 35m40sec into the video.
Since the use of the UITableView is really just a UIScrollView for the purposes of the background, you could just use a UIScrollView and you can either have it move on timer or events as needed.
Think of your player as moving within a stationary bounding box. The background can scroll using the aforementioned pooling method (as the background tile scrolls off the screen it is placed into a pool, and before a new tile is instantiated the pool is checked for available reusable tiles). Thirdly, your enemy objects will simply approach from either the bottom of the screen or the top.
Imagine your idea without the scrolling background (flying effect) and you should find that the problem is relatively straightforward.
I also needed and endless scrolling background layer. This can do exactly that, and it is super simple to set up and use. Just copy the four files in to the cocos2d folder in your project, then follow the quick tutorial seen on the github. Make sure the image you use is seamless (when you line them up vertically you can't tell where one ends.
I am in process of creating a multiplayer game similar to the Scrabble / Wordfued / Rummi. I am trying to see what would be best way go about implementing the UI and their interactions.
I would be having a framework which would keep track of all the pieces on the board and the AI for knowing if it is a valid move.
I am trying to figure out what could be best solution to handle the UI part. The game board would be larger than would the current iPhone screen could support. So the board would have an effect of a scroll view. The same goes for the game tiles using which user can play. These are not fixed amount of tiles/cards and the same could be more in numbers which would also need another scroll view kind of effect.
There would be many more effect's were the user can move a complete set of tiles/cards from the board and place it in another location of the board. Or even a tile in between the set of tiles on the board.
So I am trying so see if I should go with two scroll view provided by iOS and handle all the detaching the tile/card from one scroll view and placing the same in GameBoard scroll view
Or
Should I go with something like cocos-2d which provides more advance game UI handling capabilities.
Please do let me know your thoughts and feedback on what could be the best choice for the same. Thanks in advance for all your help.
Words With Friends uses native UIKit views. It is quite simple and uses a transition to move between the two degrees of magnification (close up and not close up).
You can do everything quickly in UIKit with a UIScrollview. You can use drag events to move tiles around the screen, even changing their perspective/look during dragging. Using UIAnimation would allow you to do simple frame based animation for things like dropping a tile.
Cocos2d will be quicker if you already know a similar gaming library. However if you choose it you you'll miss out on using Interface Builder and a lot of conveniences in UIKit.
If you're starting from a base of zero with either approach, then only use Cocos2d if you want particle effects (like stars and sparkles, UIKit has nothing for this).
Otherwise I'd say try UIKit, it's easier and there are more resources on the web.
