 # For information on the generic Dart part of this file, see the

 # The following section is specific to Flutter.
 flutter:
-  # This section identifies this Flutter project as a plugin project.
-  # The androidPackage and pluginClass identifiers should not ordinarily
-  # be modified. They are used by the tooling to maintain consistency when
-  # adding or updating assets for this project.
-  plugin:
-    androidPackage: com.example.citypickers
-    pluginClass: CityPickersPlugin
-
-  # 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.io/assets-and-images/#from-packages
-  #
-  # An image asset can refer to one or more resolution-specific "variants", see
-  # https://flutter.io/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
