How user-friendly is that app development using flutter to satisfy the accessibility checks compared to native implementations?
Can dart programming is completely satisfying assistive technologies?
I have not used Flutter myself but they have documentation on accessibility at https://docs.flutter.dev/development/accessibility-and-localization/accessibility
Looks like there's a class called Semantics that has a lot of what you need and a short 1 min video on YouTube that talks about that class, https://www.youtube.com/watch?v=NvtMt_DtFrQ

I’m developing a mobile application using flutter to be used in my country. i have to use Sinhalese language(SriLankan) font in the mobile UIs. I have searched in the Flutter Community and i was unable to find a proper solution.I want to know whether there is a flutter_localization library that can be used in my application?
I suggest that you use this Medium post as a guide. Although it implements Arabic and English as demonstration it will be beneficial to you since one of them is left-to-right and the other is right-to-left.
Yes you can use this article to integrate localisation in app.
Article it's really quick to integrate in app.
However if your language isn't supported by flutter_localizations library even though you can provide support using above class as mentioned on article.
here is snap
You have to implement localization in App. I found a simple example for the same here.
Does anyone know if it’s possible to develop a fully Native iOS and Android based Social Media Platform using React Native and Swift or Objective C to integrate a native instant messenger app into the newsfeed via a floating icon?
Our website is responsive and would make a great hybrid app using a native wrap but we are looking to stray away from web based solutions and want to try and build a fully native solution with React Native and possible Swift or Objective C. We discovered a decent IM sdk that is feature rich but is written in Objective C and Swift and wish to use this Instant Messaging Solution and attempt to match chat graphics with the rest of the app.
All thoughts, ideas and solutions are appreciated.
You can write code in Objective-C/Swift or Java for developing your own modules and to take advantage of native API for iOS or Android. But React-Native has some build-on modules that would simplify your workd just by writing JavaScript and that the magic of React-Native. It makes possible to build Apps in JavaScript that use real native elements and not just WebViews.
If you need to write your own modules in Objective-C/Swift or Java you should make use of the Bridge that implements React-Native for sharing data between Native-Code and Javascript code.
"Sometimes an app needs to access a platform API and React Native doesn't have a corresponding module yet. Maybe you want to reuse some existing Objective-C, Swift or C++ code without having to reimplement it in JavaScript, or write some high performance, multi-threaded code such as for image processing, a database, or any number of advanced extensions." from React-Native oficial website
I am starting to work on one big project which includes Sirikit, Game Center, Fingerprint, health kit and home kit etc.
So my doubt is can I implement those features & other features which are provided by ios using the flutter..?
Flutter can't generate bitcode. So, it can't integrate features like Siri, interactive notifications, watchOS, tvOS, Today and other modern extensions.
It compiles like it was before 2015. Before iOS extensions. With same limitations.
Yes and no - you could definitely use some and probably all of those, but you'll have to write Platform Channels. I use fingerprint for example in my app.
There may exist plugins for some of the functionality - see the flutter packages page.
I'm new to mobile phones development, but I wonder whether there is any way to develop native apps (HTML-based apps is another story) that would run both on Android and iPhone? I know that there exist applications available for both OSs, so I wonder how are they ported/developed for both targets?
You can simply have two different projects, with same design and graphics, or, you can do it with some frameworks like PhoneGap or Rhomobile.
The best way is to have two different versions of the code, so you can take advantage from the platform that you are using.

You can share a significant amount of Non-UI logic and code libraries by taking advantage of MonoTouch and MonoDroid. They are native frameworks which provide C# bindings around iPhone's and Androids native APIs. They have the added advantage of being able to develop in C# which IMHO is nicer than Obj-C and Java.
develop android apps that should support iphone,ipad,android.is there any way for developing this kind of generic app or we need to develop aps depending on mobile os
Though it is possible to create an universal application for iphone and ipad i don't think you can do the same for Android.
In my opinion it is always better to port your application to Android based on your requirements so that you can take advantages of the API's that the platform is offering you.
You can try using a framework named Titanium Appcelrator. This framework will help you target iPhone, iPad, Android with the same code base. This also lets you access most of the Native hardware features available with these platforms but not all. It seems that this also may support Blackberry soon.
We are struggling with the same question at the moment. Since we are working for Android, Maemo, Meego, iPhone and Blackberry (+Symbian 3 soon), HTML5 looked promising, and we dedicated quite some time investigating it. The end result was HTML5 is not yet ready for the development we were hoping for. It's fine if you need simple functionality, but as soon as something more advanced is needed, you need to create a different version. Even if it suits your needs, every platform requires different HTML5-to-native bridge, and every platform has a different engine. As you can see, only front end part could be partially used.
In your case, you need two different applications, one for Android, another one for iPhone/iPad. Try to see if you could take advantage of HTML5, if not, you are unfortunately stuck with separate development for some time to come. Unless you will create a web app and use it with device's browser.
You can create common functionality libraries with C or C++ and use these libraries in iPhone/iPad and use Android's NDK tool to integrate theses libraries with Android
On Android, you're using Java as the main language, and you can also use C and C++ . On iOS, you're using Objective-C as the main language, and also can use C and C++. So the common denominator would be C (at least on the iPhone there are no C++ GUI classes). I have no idea about developing on Android, but on iPhone it's no fun to purely work in C (and I'm not sure if it's even possible, maybe it is but should I when working with Objective-C/Cocoa is fun).
What you can do is write generic logic and share that between both systems, like a library. For example, I worked on a project where we used a C++ SIP/VoIP library that also compiles and runs on Symbian. It shouldn't be a big problem to write C code that can be shared between iOS and Android, as long as it is mostly about logic and not about calling system-specific stuff (you can of course include system specific stuff and guard that with #ifdef but you don't want your library to have more system-specific than system-agnostic code, I guess). For example, if you intend to write a networked game you could implement the network protocol in a way that could be shared between iOS and Android.
But as soon as you're hitting the GUI level I don't think you can share any code, and even if you could you probably don't want to because if you use the native languages/IDEs you are faster designing the GUIs each in their respective main languages/IDEs than trying to find a common way and then have to live with compromises and trying to make it work on both systems all day long. Better to implement the GUI native to each platform (e.g. Xcode has a very good graphical tool called Interface Builder that can save a lot of work/typing).
we can go for the XML VM to run the android apps in iphone.
