Dart Barrel Generator for JetBrains IDEs

Plugin for JetBrains IDEs (IntelliJ IDEA, WebStorm, Android Studio) that generates barrel files for Dart and Flutter projects.

What are barrel files?

In Dart (and other languages), a barrel file is a file that re-exports several other files from a directory, allowing you to import multiple files through a single import. This helps organize and simplify your code.

Features

• Generate barrel files recursively for the folder and its subfolders
• Generate barrel file including all files from subfolders
