Examples

For practical implementations, refer to the example repository. Here are a couple of screenshots:

 

Getting Started

To get started, you’ll need to make some configuration changes for both Android and iOS platforms.

1. Android Configuration

Update the MainActivity.kt

In your MainActivity.kt, add the following code:

package org.devio.flutter.splashscreen.example

import android.os.Bundle
import io.flutter.embedding.android.FlutterActivity
import org.devio.flutter.splashscreen.SplashScreen

class MainActivity : FlutterActivity() {
    override fun onCreate(savedInstanceState: Bundle?) {
        SplashScreen.show(this) // You can set `true` for full screen
        super.onCreate(savedInstanceState)
    }
}

Create launch_screen.xml

Create a layout file launch_screen.xml in app/src/main/res/layout:

Here, you can customize your splash screen by adding a launch_screen.png to the appropriate mipmap folders.

Optional Steps for Customization

For additional customization, you can set the status bar color in colors.xml and make the splash screen translucent in styles.xml.

2. iOS Configuration

In iOS, customize your splash screen via LaunchScreen.storyboard.Details can be found in the same example repository.

Usage

You can control the visibility of the splash screen programmatically. Here’s how:

import 'dart:async';
import 'package:flutter/material.dart';
import 'package:flutter_splash_screen/flutter_splash_screen.dart';

void main() => runApp(MyApp());

class MyApp extends StatefulWidget {
    @override
    _MyAppState createState() => _MyAppState();
}

class _MyAppState extends State {
    @override
    void initState() {
        super.initState();
        hideScreen();
    }

    Future hideScreen() async {
        await Future.delayed(Duration(milliseconds: 1800));
        FlutterSplashScreen.hide(); // hides your splash screen
    }

    ...
}

API

The following methods are available:

• show() – Opens the splash screen (Native Method).
• hide() – Closes the splash screen.

Testing

Make sure to thoroughly test your splash screen on various devices to confirm its appearance and functionality.

Troubleshooting

If you encounter any issues, here are a few troubleshooting tips:

• Ensure your launch_screen.xml and images are correctly placed in the respective directories.
• Review your MainActivity.kt code for any syntax errors or omissions.
• Check for Flutter and package version compatibility.
