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/icons/
- assets/images/
- 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: Poppins
fonts:
- asset: assets/fonts/Poppins/Poppins-Thin.ttf
weight: 100
- asset: assets/fonts/Poppins/Poppins-ExtraLight.ttf
weight: 200
- asset: assets/fonts/Poppins/Poppins-Light.ttf
weight: 300
- asset: assets/fonts/Poppins/Poppins-Regular.ttf
weight: 400
- asset: assets/fonts/Poppins/Poppins-Medium.ttf
weight: 500
- asset: assets/fonts/Poppins/Poppins-SemiBold.ttf
weight: 600
- asset: assets/fonts/Poppins/Poppins-Bold.ttf
weight: 700
- asset: assets/fonts/Poppins/Poppins-ExtraBold.ttf
weight: 800
- asset: assets/fonts/Poppins/Poppins-Black.ttf
weight: 900
- family: Trajan Pro
fonts:
- asset: fonts/TrajanPro.ttf
- asset: fonts/TrajanPro_Bold.ttf
weight: 700
