kotlinlang

[Solved] I'm testing with `buildJson` but is immutable and  I can't add new JsonElements  *Any mutable alternative in Kotlin-serialization lib?*

*My Scratch code:*
```val files = buildJsonArray {
 ficheros.forEach {
  add(buildJsonObject {
      put("name", JsonPrimitive(it))
  })
 }
}```

Ok, I resolved. *If anyone knows alternatives, I would be grateful if you post it.*

My Solution:
```val files2 = files.toMutableList()
    files2.add(buildJsonObject {
        put("name", JsonPrimitive("fich3.mp4"))
    })```


There should be a `putJsonObject`  though.
