+# To add assets to your package, add an assets section, like this:
+# assets:
+#   - images/a_dot_burr.jpeg
+#   - images/a_dot_ham.jpeg
+#
+# For details regarding assets in packages, see
+# https://flutter.dev/assets-and-images/#from-packages
+#
+# An image asset can refer to one or more resolution-specific "variants", see
+# https://flutter.dev/assets-and-images/#resolution-aware
+
+# To add custom fonts to your package, add a fonts section here,
+# in this "flutter" section. Each entry in this list should have a
+# "family" key with the font family name, and a "fonts" key with a
+# list giving the asset and other descriptors for the font. For
+# example:
+# fonts:
+#   - family: Schyler
+#     fonts:
+#       - asset: fonts/Schyler-Regular.ttf
+#       - asset: fonts/Schyler-Italic.ttf
