Removing "x86" and "x86_64" from the ndk configuration in your Flutter app's build.gradle file will have the following effects:
Reduced APK Size: The APK will no longer include native libraries for x86 and x86_64 architectures, making the APK smaller in size.
No Support for x86 Devices: The app will not run on:
Performance Impact on Emulators: x86 emulators will need to use ARM translation (slower) rather than running native x86 code.
Supported Architectures: The app will only support:
Play Store Impact: Google Play will only serve your app to ARM-based devices, not x86 devices.
This is generally a safe optimization since:
If you need to support x86 devices (rare), you should keep those entries. Otherwise, removing them is a good optimization.
Here's how to address each of these issues in your Flutter app:
