computeMessageName function
If a message is a string literal without interpolation, compute a name based on that and the meaning, if present.
Implementation
// NOTE: THIS LOGIC IS DUPLICATED IN intl AND THE TWO MUST MATCH.
String computeMessageName(String? name, String text, String? meaning) {
if (name != null && name != "") return name;
return meaning == null ? text : "${text}_${meaning}";
}
