@rGradov This is expected because return is a reserved keyword in dart. Any usage of any reserved keyword would do this. You can use prefix to avoid this.

groups:
  - path: assets/icons/
    class_name: AppIcons
    prefix: ic # Use a prefix for every file name
    package: res
    types: [ .svg ]
