flutter build web creates a nested assets folder so images are not loaded

Question

from pubspec.yaml:

flutter:
  assets:
    - assets/images/
  fonts:
    - family: NunitoSans
      fonts:
        - asset: assets/fonts/NunitoSans-Regular.ttf
        - asset: assets/fonts/NunitoSans-Bold.ttf
        - asset: assets/fonts/NunitoSans-ExtraBold.ttf
  generate: true

folders in root: [![enter image description here][1]][1]

image code:

Image.asset(
              'assets/images/temp.jpg',
              height: height * 0.5,
              width: width * 0.4,
              fit: BoxFit.fill,
            )

folders after flutter build web: [![enter image description here][2]][2]

The browser tries to get images from <domain>/assets/images/<image_name> [1]: https://i.stack.imgur.com/wPAYe.png [2]: https://i.stack.imgur.com/jDUNo.png
