LOCALIZATION_HELPER for Flutter Apps Localization #

This is a command line Dart application that helps in implementing localization in Flutter apps.

[NOTE]: You may find 'json_creator' and 'json_translator' packages on pub.dev helpful if you are doing localization of prebuilt Flutter apps.
https://pub.dev/packages/json_creator
https://pub.dev/packages/json_translator

This package intends to help Flutter developers who have already developed a Flutter app and are looking for localizing the project. This package includes two modes for implementing localization in Flutter apps: Basic Mode and Full Mode.

(A) Basic Mode includes:

  1. Import of necessary localization library in 'pubspec.yaml' file
  2. Creation of localization configuration file
  3. Running command for generation of localization files
  4. Addition of localization delegates in MaterialApp of 'main.dart' file

(B) Full Mode includes all features of Basic Mode in addition with:
=> Import of localization file in every Dart files containing values of generated keys of *.arb file and replacement of Text values with translated keys

Usage #

This program is published to pub.dev so you can use this package:

  1. As an executable by running the following commands:
dart pub global activate localization_helper

If path warning is shown, you need to add the highlighted directory to your system's "Path" environment variable for allowing the executable to run. Run the following command after adding the directory to path. This command runs the program in Basic Mode:

localization_helper

For running the program in Full Mode, execute the following command:

localization_helper -i full

Steps involved while running the program #

  1. Run the program in the project directory where localization needs to be implemented
  2. Enter 'y' for allowing the program to run
  3. The program detects whether the 'pubspec.yaml' file exists and imports necessary localization library
  4. Enter the name of your template *.arb file located at the specified path
  5. The program creates a localization configuration file named 'l10n.yaml' in the working directory and also adds localization delegates in 'main.dart' file
  6. When executed in Full Mode, the user needs to provide the path of the directory for replacing Text values with localization callers in every Dart files from where JSON file was created (using JSON_CREATOR)

Output #

Output is shown in console where every executions are shown with details.

Additional Information #

When used in Full Mode, this program replaces all matched const Text widgets with normal Text widgets with non constant values. You can use this regex in the search field for all files to remove const keyword for widgets wrapping matched Text widget:

(const )(\w*[([]((\r?\n?).*){0,5}S.of\(context\))

by replacing with this expression: '$2' in VS Code.

It's advisable to perform replacing operations one by one so that unexpected errors can be minimized.

There's an interesting article that can be helpful when working with arb files for localization. You can check this out: https://yapb.dev/tips-and-tricks-13-tips-when-working-with-arb-files-for-localization

Use the package and feedback is welcome! 😊💖
