Flutter Splash screen with a nice fade animation

A light weight package for flutter apps, that easily shows a splash screen with a nice fade animation.

Things to do

  1. Get a logo for your app
  2. Prepare what to execute while the splash screen is shown (initializing your db, shared preferences, firebase…etc)
  3. Screen to be shown after splash screen and background process
  4. Duration of Splash Screen.

Install

environment:
  sdk: ">=2.1.0 <3.0.0"

Add dependency in pubspec.yaml

dependencies:
  animated_splash: ^1.0.0

Import the package

import 'package:animated_splash/animated_splash.dart';

Show splash screen for some duration

  type: AnimatedSplashType.StaticDuration

Inside your main function, use home as SplashScreen(_), the parameters are as follows:

imagePath: Path to your app-logo/image home: Screen to be shown after splash duration: duration of splash screen in milliseconds type

runApp(MaterialApp(
  home: AnimatedSplash(
              imagePath: 'assets/flutter_icon.png',
              home: Home(),
              duration: 2500,
              type: AnimatedSplashType.StaticDuration,
            ),
));

Execute a function in background and based on the value from that function navigate to different screen

  type: AnimatedSplashType.BackgroundProcess

Create an object of Function that gets executed while splash screen is shown

Function duringSplash = () {
  //Write your code here
  ...
  return value;
};

Create routes according to your function return value

  //setup the return value correctly for proper navigation
  Map<dynamic, Widget> returnValueAndHomeScreen = {1: Home(), 2: HomeSt()};

              customFunction: duringSplash,
              duration: 2500,
