asset_missing_path

Asset map entry must contain a 'path' field.

The analyzer produces this diagnostic when an asset map is missing a path value.

The following code produces this diagnostic because the asset map is missing a path value:

name: example
flutter:
  assets:
    - flavors:
      - premium

Change the asset map so that it contains a path field with a string value (a valid POSIX-style file path):

name: example
flutter:
  assets:
    - path: assets/image.gif
      flavors:
      - premium
