How to remove white screen in ionic application - authentication

Question

I have created an ionic application and when I load my application after splash screen and before login page a white flicker comes for about 3-4 seconds. But I want to remove it in my application .So please suggest how to do it.
<preference name="SplashMaintainAspectRatio" value="true" />
<preference name="FadeSplashScreenDuration" value="300" />
<preference name="SplashShowOnlyFirstTime" value="false" />
<preference name="SplashScreen" value="screen" />
<preference name="SplashScreenDelay" value="3000" />

Answer 1

first you have to add below preference in config.xml file
<preference name="SplashMaintainAspectRatio" value="true" />
<preference name="FadeSplashScreenDuration" value="300" />
<preference name="FadeSplashScreen" value="true" />
<preference name="AutoHideSplashScreen" value="false" />
<preference name="ShowSplashScreen" value="true" />
then use this "cordova-plugin-splashscreen" and check this link to add this plugin
splash screen cordova plugin
and in app.component.ts in intializeApp folder or in custructor put this code
this.platform.ready().then(() => {
this.splashScreen.hide();
});
and make sure when you make production build then use ionic cordova build android --prod.
I hope this will help you.
