Is it really possible to code only once and run it without changes cross-platform on Windows, MacOS, Linux, iOS, Android and Web? Make and host interactive websites like e.g. web shops?
How do you like GUI-development with those tools, and could they also handle e.g. crypto, AI or desktop automation tasks?
Are there any (recommendable) books about Dart and Flutter? Is there enough documentation in general to get everything done that can be done without too much headache? How did you become proficient in Dart & Flutter?

I have an app that creates video montages. I'm using FFmpeg to make the montages but I would like to know if there is other packages that could accomplish the same thing.
The video_manipulation package offers an alternative (for iOS only) and is not supporting ffmpeg because:
FFmpeg won`t be implemented due to licensing, extra overhead from the ffmpeg binaries and overall slow performance.
The package is based on AVFoundation.
The tapioca package offers another alternative (for Android and iOS) and is currently based on AVFoundation for iOS and Mp4Composer-android for Android.

I want to know how to create service in flutter that service work in background of app.Any example about that.I researched but it but couldn't find a solution to do. for android and ios
I had the same problem to solve in one of my projects.
Unfortunately, Flutter does not provide any way to implement always-on service.
Moreover, iOS does not allow anything like this unless you are running some predefined services like Music Player.
So we can implement this natively as follows(with some limitations on iOS):
Android:
I implemented Foreground Service in Android. https://developer.android.com/guide/components/services#StartingAService
Then, I used MethodChannels to start and stop the service from Flutter.
https://flutter.dev/docs/development/platform-integration/platform-channels
iOS:
Only specific background tasks are allowed on iOS. Check below:

I am trying to convert word(.doc) into PDF on iOS device. Is there an opensource solution where I can use as a C/C++ lib or something?
There really is no conveniently open-source library that will do this for you: you may get some mileage out of WvWare but I've never seen it used on iOS and I'm not sure what platform dependencies it may need.
If your iphone is connected to the net, then you can call a Docmosis web service to do it. You need to sign up though.

I need to develop antivirus software for Windows. Where can I download viruses or virus-like programs to test it with?
The EICAR test file is a good start, as it is an example of a self modifying program -- something that malware usually does.
Try one of the many fake antimalware programs out there. Some SO scrapers "featured" one recently, links are in meta stack overflow.
Possibly, make sure you try them in a virtual machine disconnected from the internet. ;)
