Splash Screen is the first screen that we see when we run our application. It is also known as Launch Screen. We will implement three basic methods to add a splash screen in our app.

Steps :

1. Create a new Flutter app using Command Prompt.

2. Delete the code from main.dart file and copy the below code.

Explanation of above code :

• We have a main() function which calls runApp() by taking any widget as an argument to create the layout.
• Then we have the home as MyHomePage() which is a stateful class(Mutable class).
• MyHomePage() returns a Container which has a child as FlutterLogo(which will be shown initially when app starts).
• Now, we have one most important method which is initState().
• initState() method called once when the stateful widget is inserted in the widget tree.
• initState() first call super.initState() and then Timer of duration 4 seconds(Timer function has 2 arguments,first is Duration and second is action to be performed). After 4 seconds,Current screen will be replaced by new Screen i.e. SecondScreen() .
• We can also use Asset Image/Network Image instead of FlutterLogo.
