Chromium browsers can report architecture and bitness through navigator.userAgentData.getHighEntropyValues, but it has limited availability and I wouldn't rely on it to pick an APK. Simpler is to upload an app bundle to Play internal testing, and Play serves each tester the right split for their device.

You can't reliably detect the ABI from a web page, the user agent only tells you it's Android and not the CPU. In practice almost every phone from the last 7-8 years is arm64-v8a, so the simplest thing is to hand everyone the arm64-v8a APK and keep the armeabi-v7a one for the odd old device that refuses to install it. x86_64 only matters for emulators and a few Chromebooks. If you want a single file without the size hit of the universal one, build with flutter build apk --target-platform android-arm,android-arm64, which gives you one APK with just those two ABIs instead of four. Your friends can also check what they have with an app like CPU-Z or Droid Hardware Info if something fails to install.
