How to add Bluetooth to capabilities in Flutter Windows App - c++

I am creating flutter windows plugin with c++ which uses bluetooth device. The problem is my app is crashing just before I start scanning because of similar reason as this.
In the answers, they suggested adding bluetooth in Capabilities in appxmanifest in windows. But how can I do this for flutter project? I tried msix package for this, but to no avail. I would really appreciate your help if you could help me on this!

MacOS - How to deploy C++ application

I'm having really hard time figuring out, how to deploy C++ application in macOS. By deploying I mean a package which contains frameworks, resources and an unix executable so anyone who downloads my app will be able to run it without any further configuration.
Thanks in advance for all responses.
One solution should be to download Xcode from the appStore (free) : all needed tools to build an application bundle, a command line tool, a framework or a library are available in the software.
When building an application having a user interface, some codes in objective-c or swift are required at some point to communicate with the Cocoa frameworks, but for a command line tool it could be pure C/C++. Here is a link to a tutorial about that specific case.

Flutter Build For Android and IOS Issue

I'm having a hard time to find how to build the .apk and .ipa on Flutter.
I'm using Android Studio to make the apps, but I have no ideia on how to build it and I can't find any tutorial or documentation showing how to do it. I need to know how viable is it, because I pretend to create a lot of apps and grow on Flutter developing, so I need to know how to build and deploy my apps.
I'm just starting at Flutter developing, so I'm very beginner.
I'm using windows, can I build and deploy my apps, both for Android and IOS on it?

How to synchronize ios device contact with qt app?

I want to sync up iOS device contacts with an application based on QT platform, I am in search of an API which can do this with qt
I find workaround (QT-JNI-Java bridge) for android.
http://doc.qt.io/qt-5/qandroidjniobject.html#details
It is working fine, but i didn't find any bridge for ios.
Note: QT has suggested following link
https://wiki.qt.io/Category:Developing_with_Qt::QtMobility
But it is related to Nokia Ovi store (which doesn't exist anymore) and the last date mentioned is 2011. The link to a release is dead.
If you come across any workaround for ios-qt, request you to suggest me.
Thanks in advance.
You can use the V-Play API for a cross-platform solution to handle phone contacts on iOS & Android.
These are the APIs:

Yes you can. Just use the Attach to process.. option to connect to a running UWP app.

Does a Qt application work in Google Native Client?

I'm not familiar with Qt or with Google Native Client. Is it possible for a TRIVIAL Qt console application to be ported to Google Native Client? I understand that some work would be involved. But the question is, how much if it's even possible?
A Qt developer has managed to get some Qt examples running under Native Client:
http://blog.qt.io/blog/2009/12/17/take-it-with-a-grain-of-salt/
Qt now has an official Native Client SDK:
http://qt-project.org/wiki/Qt_for_Google_Native_Client
Qt for Google Native Client Preview also updated here: http://qt-project.org/wiki/Qt_for_Google_Native_Client
Since you can't use system calls, you'd need to essentially port Qt to a new OS (ie, Native Client). This'll be a lot of work - good luck!
For those who are interested in using Qt with NaCl, I have made a Docker image containing Qt compiled with NaCl :
Link to Docker Image
You will just need to follow the instructions to get your application compiled.
There is also a video showing the process of compiling Qt with NaCl. At the end of this video, there is an example:

Hope this help
