Description

What is a splash screen?

“A splash screen is a graphical control element consisting of a window containing an image, a logo and the current version of the software. A splash screen usually appears while a game or program is launching.” —  Wikipedia

What is the purpose of a splash screen?

“Splash screens are typically used by particularly large applications to notify the user that the program is in the process of loading. They provide feedback that a lengthy process is underway.” — Wikipedia

Why I am doing this?

Android applications do set aside some measure of opportunity to fire up, particularly on a chilly begin. There is a deferral there that you will most likely be unable to maintain a strategic distance from. Rather than leaving a clear screen amid this time, for what reason not demonstrate the client something pleasant? This is the approach Google is upholding. Try not to squander the client's chance, yet don't demonstrate to them a clear, unconfigured segment of the application the first occasion when they dispatch it, either.

In the event that you take a gander at late updates to Google applications, you'll see suitable employments of the sprinkle screen. Investigate the Flutkart application, for instance.

The measure of time you spend taking a gander at this sprinkle screen is precisely the measure of time it takes the application to design itself. This is on an icy dispatch which implies this is the slowest dispatch conceivable. In the event that the application is reserved, the sprinkle screen will leave very quickly.

Actualizing a Splash Screen

Actualizing a splash screen the correct way is somewhat not quite the same as you may envision. The splash view that you see must be prepared quickly, even before you can swell a format record in your splash action.

Import image

We need to import the image files into the project. It is common practice to put image files in a images or assets folder at the root of a Flutter project.

Drawable Background

So you won't utilize a design record. Rather, indicate your sprinkle screen's experience as the action's subject foundation. To do this, first make a XML drawable in res/drawable.

<?xml version="1.0" encoding="utf-8"?>
(html comment removed:  Modify this file to customize your launch 
 splash screen )
<layer-list 
xmlns:android="http://schemas.android.com   
   pk/res/android">
   <item 
 android:drawable="@android:color/white" />

   (html comment removed:  You can insert your own image assets here )
   (html comment removed:  <item>
        <bitmap
            android:gravity="center"
            android:src="@mipmap/launch_image" 
    />
        </item> )
    </layer-list>

Code Source

Here, I've set up a foundation shading and a picture.

Next, you will set this as your splash action's experience in the topic. Explore to your styles.xml record and include another subject for your splash action:

<resources>
   <style 
    name="LaunchTheme"parent="
  @android:style/Theme.Black.NoTitleB 
    ar">
       (html comment removed:  Show a splash screen on the activity. 
   Automatically removed when
         Flutter draws its first frame )
   <itemname="android:windowBackground">
   @drawa 
    ble/launch_background</item>
   </style>
  </resources>

Splash Theme

In your new SplashTheme, set the window foundation ascribe to your XML drawable. Arrange this as your sprinkle action's subject in your AndroidManifest.xml:

    <activity
        android:name=".MainActivity"
        android:launchMode="singleTop"
        android:theme="@style/LaunchTheme"
       android:configChanges="orientation|
        keyboardHidden|keyboard|screenSize|
      locale|layoutDirection|fontScale|
    screenLayout|density"
        android:hardwareAccelerated="true"
               
     android:windowSoftInputMode=
   "adjustResize" 
  >
        (html comment removed:  This keeps the window background of 
    the activity showing
             until Flutter renders its first frame. It can 
     be removed if
             there is no splash screen (such as the 
    default splash screen
             defined in @style/LaunchTheme). )
        <meta-data
            
    android:name="io.flutter.app.android.
   SplashScreenUntilFirstFrame"
            android:value="true" />
        <intent-filter>
            <action 
     android:name="android.intent.action.
   MAIN"/>
            <category 
      android:name="android.intent.category.
    LAUNCHER"/>
        </intent-filter>
        </activity>

Splash activity

At long last, your SplashActivityclass should simply forward you along to your fundamental movement:

 protected void onCreate(Bundle 
  savedInstanceState) {
    super.onCreate(savedInstanceState);
 GeneratedPluginRegistrant.registerWith(this);
  }
 }

Code Source

Notice that you don't set up a view for this SplashActivity. The view originates from the topic. When you set up the UI for your sprinkle action in the topic, it is accessible quickly.

On the off chance that you had a format petition for your sprinkle movement, that design record would be obvious to the client simply after your application has been completely instated, which is past the point of no return. You need the sprinkle to be shown just in that little measure of time before the application is instated.

Doing it Right

With these means finished, you will have a splash screen actualized the correct way:

Equipped with this information, influence your sprinkle to screen work the correct way. Try not to squander the client's chance, however give them something pleasant to take a gander at while they pause.

Summary

In this tutorial I explained how to make a splash screen in flutter with a timer.
