I wanna perform like find differences game in a a flutter app but I did not find any package can help so the idea is that I have two similar images with some differences like removed parts of color change parts and I want to find the exact location of this differences so that I can make it clickable to tell app that user select right difference or not
I will appreciate an help and if there is another idea I will be happy to hear

I'm currently developing an App in Flutter which i need to display 3D models. I know. Flutter is, at least at the moment, not the best choice (or shouldn't be even a choice) to build 3d apps but unfortunately i didn't know this when i started developing. I managed to render a simple '.obj' file with a simple engine I found on the internet:
https://levelup.gitconnected.com/a-simple-3d-engine-in-flutter-cc4a7edc943e
Now my problem:
My app needs to contain multiple hundred 3D models so I need to reduce the app's size. I experimented with openCTM to compress my '.obj' models and got a good result.
Now i want to display these '.ctm' files in my app. And thats the point where I got stuck.
I've researched for days if there's a sample or a tutorial to solve my problem but I haven't found one.
I've read the official openCTM documents and found openCtm reader ported to javascript (https://github.com/jcmellado/js-openctm) and dart (https://github.com/nelsonsilva/dart-openctm). And now I dont know where to begin.
I guess I need to, if my problem is solvable in flutter, modify the engine im currently using and add the openCTM reading part to it.
I hope that anyone of you can help me with my problem. Maybe even solved it already. Furthermore I hope I explained my problem clear enough.
If you can provide a native solution it would helpful, too.
Thank you in advance!
I've got an application built in flutter where we have a page transition that currently just sticks to pretty out of the box stack/slide.
We're trying to create a page curl effect similar to https://www.youtube.com/watch?v=e1znh05-iXY on the transition but not having much luck faking it with 2D animation/clip-path coupled with the gesture controlling the path similarly to the video being extremely difficult, almost impossible
Until we have some sort of 3D support within Flutter - the only way to do it that I can think of is using Unity3D via https://pub.dartlang.org/packages/flutter_unity_widget
But I don't know how this will work when we need it for every page?
OR
Going the other way and importing our Flutter app as a library in Unity to render every page within Unity.
Could I please gets some thoughts on whether either approach will work and any advice on a potential path forward?
Thanks in advance guys.
see this plugin, it's close to what you need you can take inspiration :)

I am posting the question again with more clarity.
I am trying to develop a component similar to the UI for timeline component in "Timeli" app.Ia m not sure how to start or which iOS controls to use for this .The requirement is to show the years in a horizontal table view.Pinching on the tableview should expand that particular cell and at some particular point the cell should break into the different months in that year.If the user further try to expand a particular cell by pinching then that cell should break into the different days .Reverse should also work.It would be great if anyone can help me with some tips or suggestions to star developing this.
I don't know that particular app, but I can give some general advice: browse through the open source components at Cocoa Controls; find one that is similar to what you want to create; download the source code and study it.
Even if you can't find exactly what you want, you might learn some techniques that will help you figure out how to build the control you want to build.
If you want more specific help, you're going to have to make an attempt, and then ask a specific question where you explain what you're doing and what's not working. Generic "how do I build this?" questions don't usually work too well here, because nobody knows where you are starting from.
I'm currently working on an iPhone project where i want to present to the user spesific terms from wikipedia. I'm facing tow difficulties right now:
1. I want the specific content to work offline.
2. I want to show the relevant pictures as well.
I need to find the most efficient way to do it, can someone advise ?
You could get the content online and cache them in the app DB. If necessary you could prepolutate the db directly in you app. That way some terms would already be available.
I think I am going to ask very stupid Question here. In my current project i want to give search feature. I have an big image tutorial with lot of information about on a topic and i want to search feature in the image. Suppose use type like "Apple" it will show the Apple occurred how many times in the image and after clicking on of that the image scroll and go to the position where "Apple" is occurred.
Thanks for reading my stupid question but if it is possible let me know and put some sample code??
Here is a broad overview of the approach I would take:
Find a C/C++ based OCR library
Get it to compile on the iPhone
Create a UI to feed images to the OCR library
Store output of OCR, including words found and their location in the image.
Create a UI to allow users to enter a search.
Search OCR output for matches and highlight the location of matches on the image.
I imagine step 2 is going to be the most difficult. Tesseract may work, it is C++ based but I don't know what dependencies it has.
UPDATE: Someone on GitHub has posted a demo iPhone App that uses Tesseract.
Please try to do use WebView or Core Text to render you tutorial, in which search functionality comes pretty much for free. Use OCR for search is just not practical for your need.
