Why does my Flutter app show a white screen for few seconds on start? How do I solve this issue?

On the right in the properties, there is the background attribute. Clicking on this and choosing custom will allow you to define the RGB value you'd like the colour of the white screen to now appear as. Running your app on Android and iOS will now no longer show the annoying white screen.
Open the Settings app and tap Apps & notifications. Find and tap on the app that you think is causing the problem. Tap Storage & cache and then tap Clear cache followed by Clear storage.
To solve this problem, simply open index. html from the build/web/ folder and edit it. Remove this Line or remove '/' from the href attribute. Now, after removing or editing this line, re-upload the index.
If you see the black window background of the activity showing until Flutter renders its first frame, add this on your AndroidManifest, between < activity> ... < /activity>
<meta-data android:name="io.flutter.embedding.android.SplashScreenDrawable" android:resource="@drawable/launch_background" /> You can use the package flutter_native_splash to add native splash screens for Android and iOS without the manual changes described in other answers.
The package does the manual changes for you.
1 - Depend on it:
dev_dependencies:
flutter_native_splash: ^0.1.4
And flutter pub get
2 - Configure your splash screen on pubspec.yaml:
flutter_native_splash:
image: assets/images/splash.png
color: 42a5f5
3 - Run the package
flutter pub run flutter_native_splash:create
Splash screens are now generated.

Android - Now you can change in
/AndroidStudioProjects/vendowallet/android/app/src/main/res/drawable/launch_background.xml
Something like
<!-- You can insert your own image assets here -->
<item>
<bitmap
android:gravity="center"
android:src="@mipmap/ic_launcher" />
</item>
IOS
Change the LaunchImage in Assets.xcassets
