Tools for managing Flutter applications.

pub package

alex - command line tool for working with Flutter projects.

Getting started #

Installing #

It's recommended to install the package globally and use as an executable.

You can install the package from the command line:

with pub:

$ pub global activate alex

with Flutter:

$ flutter pub global activate alex

And follow the instructions (you should add PATH variable on unix systems).

Now you can execute commands with

$ alex

⚠️ Attention! If you have only Flutter installed and doesn't have separate Dart SDK installed, then you haven't pub command. So when you try to run alex you will see something like:

~/Development/flutter/.pub-cache/bin/alex: line 17: pub: command not found

There are more than one solution for this. You can just install seperate Dart SDK if you want.

Or, if you don't want to do it, you can edit specified file (~/Development/flutter/.pub-cache/bin/alex in this example). All you need to change in it - it's use flutter pub instead of pub, so replace pub global run alex:alex "$@" with flutter pub global run alex:alex "$@", save the file, and you are all set.

Usage #

alex is working in the current directory. So if you want to work with a specific project, you should run the command in project's root directory.


To provide more convinient way to work with project, alex can use some configuration. You can define configuration in your project's pubspec.yaml, section alex, or in separate file alex.yaml.

You can see all configuration options and it's default values in the example config /alex.yaml.

More about specified configuration parameters - in modules descriptions in the Commands section.

Import translations from XML

It's for working with translations from Google Play.

You can export xml translations to the project arb translations:

alex l10n from_xml

Also you can export to the Android localization:

alex l10n from_xml --to=anroid

And to the iOS localization:

alex l10n from_xml --to=ios

Localization xml files for iOS should start with ios_ prefix.

Import translation from Google Play to project XML files

When you download and unzip translations from Google Play, you need to import them in project's xml files. You can copy it all manually, but it's very inconvenient. So you can use the command import_xml to do it.

alex l10n import_xml --path=path/to/dir/with/translations
