How to set Custom View as Real Splash Screen in Flutter Android
In Flutter documentation it is not mentioned that you Flutter Activity also has the method provideSplashScreen that can be overriden. So, I looked at the list of overrides that FlutterActivity provide and saw the method provideSplashScreen there. and it worked.
for someone else who find themselves in same situation
Just override provideSplashScreen method in you MainActivity that extends FlutterActivity
public class MainActivity extends FlutterActivity {
@Nullable
@Override
public SplashScreen provideSplashScreen() {
return new MySplashScreen(); //Your Custom Splash Screen
}
}
class MySplashScreen implements SplashScreen {
@Nullable
@Override
public View createSplashView(@NonNull Context context, @Nullable Bundle savedInstanceState) {
return LayoutInflater.from(context).inflate(R.layout.splash_screen, null, false);
}
@Override
public void transitionToFlutter(@NonNull Runnable onTransitionComplete) {
onTransitionComplete.run();
}
}

I am trying to show a custom view as real splash screen that pops up when flutter is initialising its first frame. I am following the documentation but as it says we need to create a flutter fragment and override provideSplashScreen method. I did that but I don't know how to add that fragment to the activity or how to reference that fragment in the manifest.
My Manifest File
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.neer.neer"> <!-- io.flutter.app.FlutterApplication is an android.app.Application that calls FlutterMain.startInitialization(this); in its onCreate method. In most cases you can leave this as-is, but you if you want to provide additional functionality it is fine to subclass or reimplement FlutterApplication and put your custom class here. --> <application android:name="io.flutter.app.FlutterApplication" android:icon="@mipmap/ic_launcher" android:label="neer"> <activity android:name=".MainActivity" android:configChanges="orientation|keyboardHidden|keyboard|screenSize|smallestScreenSize|locale|layoutDirection|fontScale|screenLayout|density|uiMode" android:hardwareAccelerated="true" android:launchMode="singleTop" android:theme="@style/LaunchTheme" android:windowSoftInputMode="adjustResize"> <meta-data android:name="io.flutter.embedding.android.FlutterFragment" android:value=".MyFlutterFragment" /> <!-- Specifies an Android theme to apply to this Activity as soon as the Android process has started. This theme is visible to the user while the Flutter UI initializes. After that, this theme continues to determine the Window background behind the Flutter UI. --> <meta-data android:name="io.flutter.embedding.android.NormalTheme" android:resource="@style/NormalTheme" /> <!-- Displays an Android View that continues showing the launch screen Drawable until Flutter paints its first frame, then this splash screen fades out. A splash screen is useful to avoid any visual gap between the end of Android's launch screen and the painting of Flutter's first frame. --> <meta-data android:name="io.flutter.embedding.android.SplashScreenProvider" android:resource=".MyFlutterFragment" /> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <!-- Don't delete the meta-data below. This is used by the Flutter tool to generate GeneratedPluginRegistrant.java --> <meta-data android:name="flutterEmbedding" android:value="2" /> </application> </manifest>
My MainActivity.java
package com.neer.neer; import android.animation.Animator; import android.animation.ObjectAnimator; import android.content.Context; import android.os.Bundle; import android.os.PersistableBundle; import android.view.LayoutInflater; import android.view.View; import android.view.animation.LinearInterpolator; import androidx.annotation.Nullable; import io.flutter.embedding.android.FlutterActivity; import io.flutter.embedding.android.SplashScreen; class MainActivity extends FlutterActivity { @Override public void onCreate(@Nullable Bundle savedInstanceState, @Nullable PersistableBundle persistentState) { super.onCreate(savedInstanceState, persistentState); } }
MyFlutterFragment.java file. I Need this fragment to show as splash screen
package com.neer.neer; import android.graphics.drawable.Drawable; import io.flutter.embedding.android.DrawableSplashScreen; import io.flutter.embedding.android.FlutterFragment; import io.flutter.embedding.android.SplashScreen; public class MyFlutterFragment extends FlutterFragment { @Override public SplashScreen provideSplashScreen() { // Load the splash Drawable. // Drawable splash = getResources().getDrawable(R.drawable.my_splash); // Construct a DrawableSplashScreen with the loaded splash // Drawable and return it. // return new DrawableSplashScreen(splash); return new MySplashScreen(); } }
MySplashScreen.java file.
package com.neer.neer; import android.content.Context; import android.os.Bundle; import android.view.LayoutInflater; import android.view.View; import androidx.annotation.NonNull; import androidx.annotation.Nullable; import io.flutter.embedding.android.SplashScreen; public class MySplashScreen implements SplashScreen { @Nullable @Override public View createSplashView(@NonNull Context context, @Nullable Bundle savedInstanceState) { return LayoutInflater.from(context).inflate(R.layout.splash_screen, null, false); } @Override public void transitionToFlutter(@NonNull Runnable onTransitionComplete) { onTransitionComplete.run(); } }
spash_screen.xml file (Layout for the splash screen)
<?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@android:color/background_dark" > <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="N E E R" android:layout_gravity="center" android:textColor="@android:color/white" android:textSize="@android:dimen/notification_large_icon_width" android:textStyle="bold" /> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal|bottom" android:text="Powered by ICCW" android:textColor="@android:color/white" android:textSize="26sp" android:layout_marginBottom="20dp" /> </FrameLayout>
