-name: ios_add2app_flutter
-description: A new flutter module project.
-
-# The following defines the version and build number for your application.
-# A version number is three numbers separated by dots, like 1.2.43
-# followed by an optional build number separated by a +.
-# Both the version and the builder number may be overridden in flutter
-# build by specifying --build-name and --build-number, respectively.
-# Read more about versioning at semver.org.
-#
-# This version is used _only_ for the Runner app, which is used if you just do
-# a `flutter run` or a `flutter make-host-app-editable`. It has no impact
-# on any other native host app that you embed your Flutter project into.

-  # To add Flutter specific 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.dev/assets-and-images/#resolution-aware.
-
-  # For details regarding adding assets from package dependencies, see
-  # https://flutter.dev/assets-and-images/#from-packages
-
-  # To add Flutter specific 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

-  # For details regarding fonts from package dependencies,
-  # see https://flutter.dev/custom-fonts/#from-packages
-
-  # This section identifies your Flutter project as a module meant for
-  # embedding in a native host app.  These identifiers should _not_ ordinarily
-  # be changed after generation - they are used to ensure that the tooling can
-  # maintain consistency when adding or modifying assets and plugins.
-  # They also do not have any bearing on your native host application's
-  # identifiers, which may be completely independent or the same as these.
