+flutter_native_splash:
+  # This package generates native code to customize Flutter's default white native splash screen
+  # with background color and splash image.
+  # Customize the parameters below, and run the following command in the terminal:
+  # flutter pub run flutter_native_splash:create
+  # To restore Flutter's default white splash screen, run the following command in the terminal:
+  # flutter pub run flutter_native_splash:remove
+
+  # color or background_image is the only required parameter.  Use color to set the background
+  # of your splash screen to a solid color.  Use background_image to set the background of your
+  # splash screen to a png image.  This is useful for gradients. The image will be stretch to the
+  # size of the app. Only one parameter can be used, color and background_image cannot both be set.
+  color: "#ffffff"
+  #background_image: "assets/background.png"
+  
+  # Optional parameters are listed below.  To enable a parameter, uncomment the line by removing 
+  # the leading # character.
+
+  # The image parameter allows you to specify an image used in the splash screen.  It must be a 
+  # png file and should be sized for 4x pixel density.
+  image: assets/app_icon.png
+
+  # The color_dark, background_image_dark, and image_dark are parameters that set the background
+  # and image when the device is in dark mode. If they are not specified, the app will use the
+  # parameters from above. If the image_dark parameter is specified, color_dark or 
+  # background_image_dark must be specified.  color_dark and background_image_dark cannot both be
+  # set.
+  #color_dark: "#042a49"
+  #background_image_dark: "assets/dark-background.png"
+  #image_dark: assets/splash-invert.png

+  # The android, ios and web parameters can be used to disable generating a splash screen on a given 
+  # platform.
+  #android: false
+  #ios: false
+  #web: false
+
+  # The position of the splash image can be set with android_gravity, ios_content_mode, and
+  # web_image_mode parameters.  All default to center.
+  #
+  # android_gravity can be one of the following Android Gravity (see 
+  # https://developer.android.com/reference/android/view/Gravity): bottom, center, 
+  # center_horizontal, center_vertical, clip_horizontal, clip_vertical, end, fill, fill_horizontal,
+  # fill_vertical, left, right, start, or top.
+  #android_gravity: center
+  #
+  # ios_content_mode can be one of the following iOS UIView.ContentMode (see 
+  # https://developer.apple.com/documentation/uikit/uiview/contentmode): scaleToFill, 
+  # scaleAspectFit, scaleAspectFill, center, top, bottom, left, right, topLeft, topRight, 
+  # bottomLeft, or bottomRight.
+  #ios_content_mode: center
+  #
+  # web_image_mode can be one of the following modes: center, contain, stretch, and cover.
+  #web_image_mode: center
+
+  # To hide the notification bar, use the fullscreen parameter.  Has no affect in web since web 
+  # has no notification bar.  Defaults to false.
+  # NOTE: Unlike Android, iOS will not automatically show the notification bar when the app loads.
+  #       To show the notification bar, add the following code to your Flutter app:
+  #       WidgetsFlutterBinding.ensureInitialized();
+  #       SystemChrome.setEnabledSystemUIOverlays([SystemUiOverlay.bottom, SystemUiOverlay.top]);
+  #fullscreen: true
+  
+  # If you have changed the name(s) of your info.plist file(s), you can specify the filename(s) 
+  # with the info_plist_files parameter.  Remove only the # characters in the three lines below,
+  # do not remove any spaces:
+  #info_plist_files:
+  #  - 'ios/Runner/Info-Debug.plist'
+  #  - 'ios/Runner/Info-Release.plist'
+
+  # To enable support for Android 12, set the following parameter to true.  Defaults to false.
