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: # dart run flutter_native_splash:create # To restore Flutter's default white splash screen, run the following command in the terminal: # dart run flutter_native_splash:remove # IMPORTANT NOTE: These parameter do not affect the configuration of Android 12 and later, which # handle splash screens differently that prior versions of Android. Android 12 and later must be # configured specifically in the android_12 section below. # 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: "#42a5f5" #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/start_logo.png # The branding property allows you to specify an image used as branding in the splash screen. # It must be a png file.
