+  # 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: "#e1f5fe"

+  # png file and should be sized for 4x pixel density.
+#  image: assets/logo_lockup_flutter_vertical.png

+  # NOTE: Unlike Android, iOS will not automatically show the notification bar when the app loads.
