flutter 학습을 위해 기록함.
앱을 시작할때 첫 화면, 즉 스플래시를 만들기 위해 flutter_native_splash 패키지를 사용함.
1) 패키지 설치
flutter pub add flutter_native_splash
2) 환경설정 파일 생성
루트 프로젝트 디렉토리에 flutter_native_splash.yaml 파일 생성하여, 아래 내용을 추가함.
- color 값과 image 경로를 원하는대로 설정
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" // 배경색깔
#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/img/splash_768.png // 스플래시 이미지를 사용할 경우, 주석 풀고 이미지 경로
# The branding property allows you to specify an image used as branding in the splash screen.
# It must be a png file. It is supported for Android, iOS and the Web. For Android 12,
# see the Android 12 section below.
#branding: assets/dart.png
# To position the branding image at the bottom of the screen you can use bottom, bottomRight,
# and bottomLeft. The default values is bottom if not specified or specified something else.
#branding_mode: bottom
# Set the branding padding from the bottom of the screen. The default value is 0
# (Not supported on web yet)
# branding_bottom_padding: 24
# The color_dark, background_image_dark, image_dark, branding_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 there is no parameter above, the app will use the light mode values.
# 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
#branding_dark: assets/dart_dark.png
# From Android 12 onwards, the splash screen is handled differently than in previous versions.
# Please visit https://developer.android.com/guide/topics/ui/splash-screen
# Following are specific parameters for Android 12+.
android_12:
# The image parameter sets the splash screen icon image. If this parameter is not specified,
# the app's launcher icon will be used instead.
# Please note that the splash screen will be clipped to a circle on the center of the screen.
# App icon with an icon background: This should be 960×960 pixels, and fit within a circle
# 640 pixels in diameter.
# App icon without an icon background: This should be 1152×1152 pixels, and fit within a circle
# 768 pixels in diameter. To fit a 1152x1152 image within a circle with a 768 diameter, simply
# ensure that the most important design elements of your image are placed within a circular area
# with a 768 diameter at the center of the 1152x1152 canvas.

# Splash screen background color.
color: "#42a5f5" // 배경색깔
# App icon background color.
#icon_background_color: "#111111"
# The branding property allows you to specify an image used as branding in the splash screen.
#branding: assets/dart.png
# The image_dark, color_dark, icon_background_color_dark, and branding_dark set values that
# apply when the device is in dark mode. If they are not specified, the app will use the
# parameters from above. If there is no parameter above, the app will use the light mode values.
#image_dark: assets/android12splash-invert.png
#color_dark: "#042a49"
#icon_background_color_dark: "#eeeeee"
# 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
# Platform specific images can be specified with the following parameters, which will override
# the respective parameter. You may specify all, selected, or none of these parameters:
#color_android: "#42a5f5"
#color_dark_android: "#042a49"
#color_ios: "#42a5f5"
#color_dark_ios: "#042a49"

# 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 can be combined using the | operator to achieve multiple effects.
# For example:
# `android_gravity: fill|clip_vertical` - This will fill the width while maintaining the image's vertical aspect ratio
#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
# The screen orientation can be set in Android with the android_screen_orientation parameter.
# Valid parameters can be found here:
# https://developer.android.com/guide/topics/manifest/activity-element#screen
#android_screen_orientation: sensorLandscape
# To hide the notification bar, use the fullscreen parameter. Has no effect 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.setEnabledSystemUIMode(SystemUiMode.manual, overlays: [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'
3) 패키지를 실행
