2 years ago @intercretasyo @SeriousMonk @puze can you provide more information?
@SeriousMonk @puze can you add your Flutter Doctor output?
Is the problem on Android 11? Are the error message happening when you run your app after having previously added the splash screen? Do the errors happen during the splash screen or after the app loads?
I am not able to reproduce these errors. Can you supply me with a means to reproduce the errors?

2 years ago Hello all, I have replicated this error.
First, create a new Flutter project and import the flutter_native_splash library. When you build and run the app, in the log, you will find this warning:
W/FlutterActivityAndFragmentDelegate(27508): A splash screen was provided to Flutter, but this is deprecated. See flutter.dev/go/android-splash-migration for migration steps.
So, remove the deprecated code, as shown in the guide..
when you build and run the app, you will find these errors:
I/ViewRootImpl@5d03b84MainActivity: [DP] cancelDraw io.flutter.embedding.android.FlutterActivityAndFragmentDelegate$2@3d78bf0 isViewVisible: true
.. tadaaan :)
For now, I've decided to ignore the deprecation warning and place this code, inside the manifest.
<!-- 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.SplashScreenDrawable"
android:resource="@drawable/launch_background"
/>
@jonbhanson Could you please let us know how to resolve the issue?
Than you, Carlo.

2 years ago Thanks for the instructions, @CarloDotLog, but unfortunately I still cannot reproduce the problem. Here is what I did:
pubspec.yaml, add flutter_native_splash: ^1.3.0 under dev_dependenciespubspec.yaml, add:
flutter_native_splash:
color: "#42a5f5"flutter pub getflutter pub run flutter_native_splash:createandroid/app/src/main/AndroidManifest.xml:

2 years ago Thank you for your reply @jonbhanson.
I confirm that if I retry the steps, I enable/disable the errors.
Without this code in the manifest file
<meta-data
android:name="io.flutter.embedding.android.SplashScreenDrawable"
android:resource="@drawable/launch_background"
/>I have the errors and a long time white screen.
I've tested on Pixel 4 (Emulator) with Android 11 and a SM A405FN (device) with Android 11 and I had the same errors.
There is my flutter doctor -v output:

2 years ago Is anyone still experiencing this problem? It seems there was a rash of these in October, and then no more. Maybe it was related to a Flutter update that had a problem and was subsequently patched?

2 years ago @jonbhanson I can confirm, that I see these messages now with my app Encrateia that I am currently updating, after having removed meta-data as above from the Android.manifest.
I am developing using flutter installed via snap within Ubuntu;
flutter doctor -v outputs:
flutter doctor -v

2 years ago Facing the same issue on Samsung M31, API31. The issue isn't reproducible on pixel devices. Reading the comments above, adding the deprecated metadata to AndroidManifest.xml manually shows a deprecation warning
W/FlutterActivityAndFragmentDelegate( 1202): A splash screen was provided to Flutter, but this is deprecated. See flutter.dev/go/android-splash-migration for migration steps.
and removes the message
I/ViewRootImpl@3aca0baMainActivity: [DP] cancelDraw null isViewVisible: true
Describe the bug More than a hundred of these lines are found: I/ViewRootImpl@50e8af1MainActivity: [DP] cancelDraw io.flutter.embedding.android.FlutterActivityAndFragmentDelegate$2@5fb73dc isViewVisible: true
