flutter:

  # The following line ensures that the Material Icons font is

  # 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

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?

What output do you have when you give the command of "flutter run" from the terminal? — Durdu
flutter build ios --release then from Xcode I'd build the archive and then export the ipa and then installed it on the device. Although apps work fine in debug mode. — Sarthak Solanki
Yes, This is not the issue thing is you can't open an ipa build with the "ios app store". If you want to check, try "ad-hoc" and make sure you have the certificate on your phone. — Sarthak Solanki

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.
