# The following section is specific to Flutter packages.
flutter:

# The following line ensures that the Material Icons font is
# included with your application, so that you can use the icons in
# the material Icons class.
uses-material-design: true

# To add assets to your application, add an assets section, like this:
assets:
- assets/
- assets/home/bg.png
- assets/home/head.png
- assets/template/sablon13.svg
- assets/fonts/NotoSans-Regular.ttf
- assets/fonts/Merriweather-Regular.ttf
- assets/fonts/Roboto-Regular.ttf
- assets/fonts/OpenSans-Regular.ttf
- assets/fonts/Lato-Regular.ttf
- assets/fonts/Montserrat-Regular.ttf
- assets/fonts/Nunito-Regular.ttf
- assets/fonts/Raleway-Regular.ttf
- assets/fonts/Poppins-Regular.ttf
# - 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.dev/to/resolution-aware-images

# For details regarding adding assets from package dependencies, see
# https://flutter.dev/to/asset-from-package

# 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: NotoSans
fonts:
- asset: assets/fonts/NotoSans-Regular.ttf
