asset_does_not_exist

The asset file '{0}' doesn't exist.

The analyzer produces this diagnostic when an asset list contains a value referencing a file that doesn't exist.

Assuming that the file doesNotExist.gif doesn't exist, the following code produces this diagnostic because it's listed as an asset:

name: example
flutter:
  assets:
    - doesNotExist.gif

If the path is correct, then create a file at that path.

If the path isn't correct, then change the path to match the path of the file containing the asset.
