I am trying to make a Flatpak for my little application “OpenSpeedTest-Server”

This is a simple network performance estimation tool. It is working fine on Windows, Mac and Linux (DEB).

1) When i Export the same in Flatpak, Application unable to get the client device ip address.

2) Also i am not able to put a custom icon for my Flatpak.

I used electronforge.

sudo flatpak install ‘/home/vishnu/Desktop/app/out/make/flatpak/x86_64/io.atom.electron.OpenSpeedTest-Server_stable_x86_64.flatpak’ --share=network
[sudo] password for vishnu:

EIther it’s set in the manifest, or you set it when running. The latter being for testing / overriding.

man flatpak-run for details

The module returns the address of the internet-facing interface, as determined from the default gateway. When the address cannot be determined for any reason, undefined will be returned.
The module relies on operating systems tools. On Linux and Android, the ip command must be available, which depending on distribution might not be installed by default. It is usually provided by the iproute2 package. .v4.sync() and .v6.sync() are not supported in browsers and just return undefined.

ip command might be the issue?

some of these utilities might not be in the sandbox and might need to be added to the manifest.
