## What it is
FlutterGen is a Dart/Flutter code generator that creates type-safe accessors for assets, fonts, colors, and other resources, eliminating String-based APIs. It runs as a build_runner integration (flutter_gen_runner) or as a standalone CLI executable (fluttergen).

## Use cases
- generate type-safe asset references in flutter
- avoid typo crashes from hardcoded asset path strings
- generate code for fonts and colors in flutter projects
- integrate asset code generation into build_runner
- generate asset accessors across dart pub workspaces
- replace string-based asset APIs with generated classes

## When to choose
- you maintain a Flutter project with many assets, fonts, or colors and want compile-time safety
- you want SwiftGen-style generated accessors for Dart/Flutter
- you use build_runner and want automatic regeneration of asset code

## When to avoid
- your project is not Flutter/Dart
- you have very few assets and string paths are manageable
- you cannot adopt build_runner or the minimum Dart SDK version
