# Both the version and the builder number may be overridden in flutter | |
# build by specifying --build-name and --build-number, respectively. | |

# The following line ensures that the Material Icons font is | |

# To add assets to your application, add an assets section, like this: | |
# assets: | |
# - images/a_dot_burr.jpeg | |
# - images/a_dot_ham.jpeg | |
# An image asset can refer to one or more resolution-specific "variants", see | |
# https://flutter.io/assets-and-images/#resolution-aware. | |
# For details regarding adding assets from package dependencies, see | |
# https://flutter.io/assets-and-images/#from-packages | |
# 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 | |
# example: | |
# fonts: | |
# - family: Schyler | |
# fonts: | |
# - asset: fonts/Schyler-Regular.ttf | |
# - asset: fonts/Schyler-Italic.ttf | |
# style: italic | |
# - family: Trajan Pro | |
# fonts: | |
# - asset: fonts/TrajanPro.ttf | |
# - asset: fonts/TrajanPro_Bold.ttf | |
# weight: 700 | |
