processAction method
Performs the action in form, within context (a repeat instance or
null for top level); returns the reference it set, if any.
Implementation
@override
TreeReference? processAction(FormDef form, TreeReference? context) {
final target = context == null
? targetReference
: targetReference.contextualize(context)!;
form.recordAudioListener?.call(target, quality);
return target;
}
