extract_messages library Null safety
This is for use in extracting messages from a Dart program
using the Intl.message() mechanism and writing them to a file for
translation. This provides only the stub of a mechanism, because it
doesn't define how the file should be written. It provides an
IntlMessage class that holds the extracted data and parseString
and parseFile methods which
can extract messages that conform to the expected pattern:
(parameters) => Intl.message("Message $parameters", desc: ...);
It uses the analyzer package to do the parsing, so may
break if there are changes to the API that it provides.
An example can be found in test/message_extraction/extract_to_json.dart
Note that this does not understand how to follow part directives, so it has to explicitly be given all the files that it needs. A typical use case is to run it on all .dart files in a directory.
- A particular message extraction run.
String name, String? text, String? meaning) → String?
- If a message is a string literal without interpolation, compute a name based on that and the meaning, if present.
