It's not working on MacOS and the web.

I tried the package on an iOS emulator and it worked flawlessly. However, when I tried it on the web and MacOS, it couldn't connect to the server.

I use this package on ios, macos, windows and android and everywhere its working.

On MacOS you need to open the project in xcode (the macos one) and enable at signing -> sandbox -> incoming & outcoming connections (for debug and release)

MacOS has some more restrictions

for people struggling with web support, check if the installed version is the latest one. For some reason,
flutter pub install installs an old version for me
