onBindViewHolder

open override fun onBindViewHolder(holder: HelpItemAdapter.HelpItemViewHolder, position: Int)

If there is a (re)usable HelpItemViewHolder: change its content.

Change the content of the HelpItemViewHolder by retrieving the help item of the current position from the data list and bind them to this HelpItemViewHolder. Also there is a observer to dyslexicFont value in armadilloViewModel. If the dyslexicFont value changes, the font of every text resource in this ViewHolder instance will be changed immediately.
