Is it possible to remove or hide the default splash screen provided by the system?

I have created a splah screen with flutter but default one i can’t remove it

here is the code:

import 'package:educationalapp/Screens/Wellcome.dart';
import 'package:educationalapp/values/colors.dart';
import 'package:flutter/material.dart';

class SplashScreen extends StatefulWidget {
  const SplashScreen({super.key});

  @override
  State<SplashScreen> createState() => _SplashScreenState();
}

class _SplashScreenState extends State<SplashScreen> {
  @override
  void initState() {
    super.initState();
    // Navigate to the Home screen after 5 seconds
    Future.delayed(const Duration(seconds: 5), () {
      Navigator.push(context, MaterialPageRoute(builder: (context) => const WellcomePage()));
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Container(
        height: double.infinity,
        width: double.infinity,
        decoration: const BoxDecoration(
          color: mainColor,
        ),
        child: const Center(
          child: Image(image: AssetImage('assets/images/logo.png')),
        ),
      ),
    );
  }
}

I’m trying to add a Flutter package to my project and was wondering about the best approach to do this. Specifically, I would like to add a package without going through the full dependency management process.

Here’s what I’ve tried:

i add flutter_native_splash package but i does not add animations that you all knows
and also flutter_animated_splash that will also show default splash screen
