Read Json File from Assets Folder and map it to a model class

ReadJsonFromAssets.kt

  //This code snippet assumes the JSON file content is an array of MODEL_CLASS objects.
  var content = emptyArray<MODEL_CLASS>()
  
  fun readJsonFile(context: Context) {
        //get an input stream from assets folder for the file
        val inputStream = context.assets.open("FILE_NAME.json")
        //get input stream size
        val size: Int = inputStream.available()
        //create a byte array of corresponing size
        val buffer = ByteArray(size)
        //read it in form of bytes
        inputStream.read(buffer)
        //close the input stream
        inputStream.close()
        //convert byte array into string(json)
        val json = String(buffer, Charsets.UTF_8)
        //Gson for desrialization
        val gson = Gson()
        //convert json string into array of model objects
        content = gson.fromJson(json, Array<MODEL_CLASS>::class.java)
