hey channel. I am still searching for a good Kotlin course to learn how to work with Kotlin Framework Collections and Streams.
Could someone please help me to convert the java.util.List<com.google.protobuf.ByteString> to ByteArray like Byte[]?

[Johann Pardanaud]

you can convert a ByteString by calling .toByteArray()

[Johann Pardanaud]

however it is up to you to know how the List<ByteArray> should be converted to a single ByteArray
