23 | flutter:
24 | 
25 |   # To add assets to your package, add an assets section, like this:
26 |   # assets:
27 |   #  - images/a_dot_burr.jpeg
28 |   #  - images/a_dot_ham.jpeg
29 |   #
30 |   # For details regarding assets in packages, see
31 |   # https://flutter.io/assets-and-images/#from-packages
32 |   #
33 |   # An image asset can refer to one or more resolution-specific "variants", see
34 |   # https://flutter.io/assets-and-images/#resolution-aware.
35 | 
36 |   # To add custom fonts to your package, add a fonts section here,
37 |   # in this "flutter" section. Each entry in this list should have a
38 |   # "family" key with the font family name, and a "fonts" key with a
39 |   # list giving the asset and other descriptors for the font. For
40 |   # example:
41 |   # fonts:
42 |   #   - family: Schyler
43 |   #     fonts:
44 |   #       - asset: fonts/Schyler-Regular.ttf
45 |   #       - asset: fonts/Schyler-Italic.ttf
46 |   #         style: italic
47 |   #   - family: Trajan Pro
48 |   #     fonts:
49 |   #       - asset: fonts/TrajanPro.ttf
50 |   #       - asset: fonts/TrajanPro_Bold.ttf
51 |   #         weight: 700
