PWA installed on Android always shows a default blue splash screen, ignoring background/theme color settings

Current Behavior

When the app is installed as a PWA on Android (added to home screen), the splash screen always shows a default blue background, ignoring any custom background or theme color settings.

Expected Behavior

The splash screen and initial loading screen should respect the configured background and theme colors defined by the developer.

When custom colors are set, the PWA should display those colors instead of the default blue background when installed on Android.

Not being able to customize this color breaks the application's visual consistency, especially when it follows a defined color palette, resulting in a poor user experience.

Steps to Reproduce

1. Create a FlutterFlow project and enable Web/PWA support

2. Add a custom "meta name="theme-color" content="#FFFFFF" in Web Deployment - Custom Headers

3.Build and deploy the web app

4.Open the app in Google Chrome on Android

5.Add the app to the home screen (install as PWA)

6.Launch the installed app

7.Observe the splash screen during startup

Result: The splash screen shows a default blue background instead of the configured color
