assets_gen

The assets_gen package helps you to generate a .dart file that contains all assets according to pubspec.yaml.

Way to reference asset path	Sample Code
Use string path directly	`Image.asset('assets/images/foo.png');`	❌ Unsafe
Use `assets_gen`	`Image.asset(Assets.assets_images_foo_png);`	✅ Good

Getting Started

dev_dependencies:
  assets_gen: any # Replace 'any' with version number.
  build_runner: any # Optional.

	Call directly (Recommend)	Use `build_runner`
Run a single build and exit.	`flutter pub run assets_gen build`	`flutter pub run build_runner build`
Continuously run builds as you edit files.	`flutter pub run assets_gen watch`	`flutter pub run build_runner watch`

More info about pub-run and build_runner.

# Specify an assets_gen section in pubspec.yaml or assets_gen.yaml
flutter:
  assets:
    - path/to/asset
assets_gen:
  ...
