Blomp

Blomp is a demo app for a library that allows Unity apps to be controlled by any phone with the companion phone app written in Flutter.

The phone scans a QR code displayed by the Unity app that contains network data.

The phone then negotiates a websocket connection with the Unity app and data can be sent bidirectionally. It can be float, int, string, or binary.

In this example, the phone allows you to take a selfie, which gets transmitted to the Unity app and becomes an entity you can control.
You can control the size of your face with a slider and trigger a "blomp" with a button.
