# The following section is specific to Flutter.
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.

  # To add assets to your application, add an assets section, like this:
  # assets:
  #  - images/a_dot_burr.jpeg
  #  - images/a_dot_ham.jpeg
  assets:
  - images/splash_screen.png
  - images/BG_Login_Flow01.jpg

  - images/BG_Login_Flow03.png
  - images/Launcher_92.png

  # An image asset can refer to one or more resolution-specific "variants", see
  # https://flutter.io/assets-and-images/#resolution-aware.

  # For details regarding adding assets from package dependencies, see
  # https://flutter.io/assets-and-images/#from-packages

  # 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: 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
  fonts:
  - family: Poppins
    fonts:
    - asset: fonts/Poppins-Medium.ttf
  - family: Roboto
    fonts:
    - asset: fonts/Roboto-Regular.ttf

UPDATE::

ok so the update is I'm unable to open ipa built by "iOS app store" option but when I built it using "development" option it works fine. Is this is how it suppose to work or it should work with "iOS app store" option also?

Answer 1

You may need commands

$ flutter logs

to read response from your iphone.

To add an icon for iOS, you would need some other packages, like "flutter_launcher_icons" or "cupertino_icons".

Take flutter_launcher_icons for example, you need to add dependancies in your pubspec.yaml,

dev_dependencies:
  flutter_launcher_icons:

flutter_icons:
  android: true
  ios: "BLE4.0"
  image_path: "assets/icon/icon.png"
  image_path_android: "assets/icon/icon.png"
  image_path_ios: "assets/icon/icon.png"

and then update your ios project file manually.
