📄 Description

Added support for QByteArray.

Create QByteArray in .NET using byte[]:

[NotifySignal("byteArrayPropertyChanged")]
public byte[] ByteArrayProperty { get; set; } = new byte[]{1,3,6,8};

Receive QByteArray in .NET:

public void Process(dynamic o) {
    byte[] bytes = (byte[])o;
    Console.WriteLine("Received byte array size: " + bytes.Length);
    ...
}

In QML, there is no direct way to access QByteArray objects, they are, however, implicitly converted to javascript ArrayBuffer objects [see: Qt docs] which can be used like this:

function logValue() {
    var data = new Uint8Array(netObject.byteArrayProperty)
    console.log("first element from byte array: " + data[0]);
}
