On iOS, when native splash screen is visible, Flutter can receive gesture events.

On iOS is possible to interact with Flutter UI when the native splash screen is still visible.

To Reproduce

import 'package:flutter/material.dart';
import 'package:flutter_native_splash/flutter_native_splash.dart';
import 'package:url_launcher/url_launcher.dart';

final Uri _url = Uri.parse('https://flutter.dev');

void main() {
  WidgetsBinding widgetsBinding = WidgetsFlutterBinding.ensureInitialized();
  FlutterNativeSplash.preserve(widgetsBinding: widgetsBinding);
  runApp(
     GestureDetector(
      onTap: _launchUrl,
      child: const MaterialApp(home: Material()),
    ),
  );
}

Future<void> _launchUrl() async {
  if (!await launchUrl(_url)) {
    throw Exception('Could not launch $_url');
  }
}

That is very interesting. However, this package only configures the appearance of the splash screen (command line util) and controls when it is removed (with the .remove method). This behavior would have to be addressed by the Flutter team. Or it might even be iOS related.

I was suspecting it...I guess it should be addressed by the flutter team then
