This is a web editor for .arb files, which are required for internationalizing flutter applications using the official method. There are other options for improving the editing experience, such as VSCode plugins.
This editor is open-sourced and free-to-use. Feel free to contribute to the project (adding features, fixing bugs).
For progress, please check trello board. I will constantly add features as well as update the progress there.
Feel free to suggest features or report bugs by creating a new issue here. I also welcome pull requests.
