Flutter App Displays Blank White UI on iOS 14 & 15, but Works Fine on Android and Other iOS Versions

[JIT-Surya]

Body

I have developed a Flutter app that functions correctly on Android and other iOS versions. However, on iOS 14 and 15, the app displays a blank white screen upon launch. This issue does not occur on other iOS versions or Android devices.

I’ve tested the app on various Android devices and iOS versions, where it works as expected. The problem persists when testing on iOS 14 and 15 simulators. I anticipated that the app would display its main content and UI elements properly across all supported iOS versions.

The minimum IOS version set in your project might not be compatible with some features used in your app. Ensure that the IOS deployment target is set to a version that supports all the features you are using. You can check or update this in your project's ios/Runner.xcodeproj settings.
