This is a fork of intl_translation to have an up to date version.
This package provides message extraction and code generation from translated messages for the Intl package. It's a separate package so as to not require a dependency on analyzer for all users.
Extracting And Using Translated Messages
When your program contains messages that need translation, these must be extracted from the program source, sent to human translators, and the results need to be incorporated.
To extract messages, run the
pub run intl_generator:extract_to_arb --output-dir=target/directory my_program.dart more_of_my_program.dart
This will produce a file
intl_messages.arb with the messages from all of these
programs. This is an ARB format file which can be used for input to
translation tools like Localizely or (the deprecated) Google
Translator Toolkit. The resulting
translations can be used to generate a set of libraries using the
This expects to receive a series of files, one per locale.
pub run intl_generator:generate_from_arb --generated-file-prefix=<prefix> <my_dart_files> <translated_ARB_files>
This will generate Dart libraries, one per locale, which contain the
translated versions. Your Dart libraries can import the primary file,
<prefix>messages_all.dart, and then call the initialization
for a specific locale. Once that's done, any
Intl.message calls made in the context of that locale
will automatically print the translated version instead of the
import "my_prefix_messages_all.dart"; ... initializeMessages("dk").then(printSomeMessages);
Once the Future returned from the initialization call completes, the message data is available.
- 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
IntlMessageclass 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 [...]
- This provides utilities for generating localized versions of messages. It does not stand alone, but expects to be given TranslatedMessage objects and generate code for a particular locale based on them. [...]
