+# The following defines the version and build number for your application.
+# A version number is three numbers separated by dots, like 1.2.43

+# Both the version and the builder number may be overridden in flutter

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

+
+  # To add custom fonts to your application, add a fonts section here,

+  # list giving the asset and other descriptors for the font. For
+  # example:
+  # fonts:
+  #   - family: Schyler

+  #       - asset: fonts/Schyler-Regular.ttf
