   # To add assets to your application, add an assets section, like this:

   assets:

     - assets/images/

+
+
     - assets/sounds/

   # An image asset can refer to one or more resolution-specific "variants", see

   # To add custom fonts to your application, 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

   fonts:
