# To add assets to your plugin package, add an assets section, like this:
|
|
||||||
# assets:
|
|
||||||
# - images/a_dot_burr.jpeg
|
|
||||||
# - images/a_dot_ham.jpeg
|
|
||||||
#
|
|
||||||
# For details regarding assets in packages, see
|
|
||||||
# https://flutter.dev/assets-and-images/#from-packages
|
|
||||||
#
|
|
||||||
# An image asset can refer to one or more resolution-specific "variants", see
|
|
||||||
# https://flutter.dev/assets-and-images/#resolution-aware
|
|
||||||
|
|
||||||
# To add custom fonts to your plugin package, 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
