android – Is there a way to change the splash screen color based on the Apps theme?-Exceptionshub

Questions:

Can the native android splash screen color be changed programmatically, so that it can be set fitting to the theme chosen for the Flutter app?

Kind of like how the WhatsApp splash screen loads in a dark theme when the System theme is set to dark.

Dark and light WhatsApp splash screen:

I guess this uses two themes for the splash screen, which are linked to the system theme, but I don’t know that much about how and if that’s possible.

So the question is: Is it possible to change the color/theme of the splash screen while running a flutter application, so that on the next start of the app the native android splash screen loads in the same theme as the Flutter app?

(Sorry if I repeated myself a lot, but I want to describe what I’m asking as good as possible)

How to&Answers:

You can use some sort of SharedPreferences to hold the current state of the Theme. Then return the desired theme to the MaterialApp based on the value saved in your Shared Preferences. I personally use HydratedBloc package to save the current states of my app, including Theme.

Answer:

If you set the splash screen from the Android folder xml files, then i guess you can’t escape writing some Native code and placing some of your theming logic in the Android subfolder. On the other hand, if the theming logic and splashscreen is both in the main.dart file. Then you can just store the two different splashscreens you want to use and add some if-else statement to display the splash screen and also save user theme preference. If you don’t know how to do this, you can follow this thread:
