Overview
r_flutter is a Flutter package that generates compile-time constants for resources such as assets, fonts, and images, enabling safe and efficient access using string references. By generating a dedicated class (e.g., R) with static properties for each resource, it eliminates the risk of typos and improves code maintainability. The generated constants are type-safe and optimized for performance, making them ideal for large-scale applications. It supports all major platforms including Android, iOS, macOS, Windows, and Linux.
Use cases
- Generating safe asset references
