Overview
Flutter Gen is a code generator for Flutter that eliminates string-based APIs by automatically generating Dart code for assets, fonts, colors, and other resources. It enhances type safety and reduces runtime errors by providing compile-time checks. Developers can access images, strings, and themes through strongly-typed constants, improving code readability and maintainability. The tool integrates seamlessly into the Flutter workflow via a simple pub add command and supports multiple platforms including macOS, Windows, and Linux.
