[FEATURE REQUEST] Broadcast/Send Message from Server without Invoking any method.

[iharoonamjad]

Is it possible to send message from Server without having to invoke any method from client.

I have a scenario where U.are.U 4500 Fingerprint reader Emits Callbacks for different interactions with the device.

I need to send data from C# to Flutter on each interaction.

Is is possible?
If yes? Can you please provide some example code.

What about making a blocking call that will return as soon 1st event occurs?
