I what to build flutter desktop application for linux ubuntu. The application needs to read from the serial port of the desktop. The use case is I will be connecting a weight machine to my desktop using RS232. Are there any API available in flutter that can read the weight and show it in the application.
As far as I know, it's only available for IOS and Android.usb_serial: ^0.2.4
More details would be helpful if you provide what exactly you want to read for alternative solutions.
Edit:
check out
flutter_libserialport: ^0.2.0 https://pub.dev/packages/flutter_libserialport/example
libserialport: ^0.2.0+2 https://pub.dev/packages/libserialport

I am trying to get windows machine information such as bios vendor, serial and other cpu info like cores, vendor, socket etc...(some static info).
I believe that I can achieve this using ffi and win32 api, but I don't have basic idea to start.
In other hand, how get these details in flutter desktop application?

I created a package to solve this, is windows_info_device will help to get more details using WMI and PowerShell.
I'm interested in hosting my flutter web app on linode.com and also using it as a backend for my flutter mobile apps as a more affordable alternative to Google Firebase and AWS.
I've seen some articles online about using Digital Ocean for flutter apps, but does anyone have an idea of how to use Linode.com for hosting Flutter apps?
Thanks again
You could use Digital Ocean tutorials for Linode.com. The main part of installing your app to server is setting up VPS, installing softwares, and many more are same on every hosting provider. The only difference might be user interface used for creating virtual server instances.
I installed rocket chat on my server and now I need to install some app, that will allowed me to call. So, I tried to install jitsi, but it doesn't work on my 3d domain (meet.myurl.com, rocket chat is working on myurl.com) and now I tried to install WebRTC, but it doesn't work for me. I haven't any notification, when I call. On mobile version I haven't some button to call. I don't know need I do some configuration with my server? I didn't find any documentation. Or may be someone know some easy variant to do voice call in rocketchat? Thanks
In my case. I just turned it on as in the picture. And video calls became possible on Android and Web-browser clients. There is no need to restart the server.

I need to connect the smartfoxserver by .dart package.
Do we have library to connect the smartfoxserver, which should support IOS, Android, Windows and web.
But we have some packages for socket.io but not available for smartfoxserver.
Can you provide me the suggestion.
I tried to create a HID over GATT device with Windows IoT Core on my Raspberry Pi 3. I followed the documentation on https://learn.microsoft.com/en-us/windows/uwp/devices-sensors/gatt-server which is not 100% accurate for the release version of the 15063 SDK but it is the only documentation I could find.
However, when calling
GattServiceProviderResult result = await GattServiceProvider.CreateAsync(
GattServiceUuids.HumanInterfaceDevice);
I get
result.Error == BluetoothError.DisabledByPolicy
I added the Bluetooth capability to my package manifest, I'm running build 15063 and I'm using 15063 as the minimum SDK version. I tried to use the code in a Background App.
Also - I don't understand the error message. I haven't done anything with policies; I'm not running the Pro version of Windows IoT Core.
As it turns out, running a HID service is not allowed according to this Microsoft answer on github.
Unfortunately, HID is currently protected as a reserved service, which prevents it from being implemented by a 3rd party application. Please share details on the scenario, and we will discuss it internally.
The documentation for GATT Server on UWP is still being worked on (https://github.com/MicrosoftDocs/windows-uwp/issues/63)
