I am currently in the master channel in Flutter on Version 2.6.0-12.0.pre.406 and every time i run an app im getting these strange messages in the console and i just wanna know why and what they mean and if i can ignore these. This even happens when i am newly creating an app and run it without editing anything. So even when i am running the example app.

This is the output:

Launching lib\main.dart on ... in debug mode...
Running Gradle task 'assembleDebug'...                              7,0s

I had the same error once I integrated Firebase into my flutter application. This may not be a legitimate solution to this error, but here is what I did.

  1. Upgraded minSdkVersion to 24(ANDROID/APP/build.gradle)

Usually firebase required us to upgrade the SDK to 19. I changed it to a higher SDK(in this case 24) for testing purposes.

  1. Clean & Build gradle

I then cleaned the our android gradle files with the following cmds;

  • cd android -> if you are at the root of your flutter project
  • ./gradlew clean -> To clean the gradle environment
  • ./gradlew build -> To build again on a clean environment
  1. Cleaned and run in the flutter environment
  • cd .. -> To return to the root
  • flutter clean -> Cleans the flutter workspace
  • flutter pub get -> Gets back the deleted packages and dependencies
  • flutter run -> Runs the application

I hope this helps out someone, as I said it is not a legitimate solution, but it is what worked for me. If this fails. Also consider checking the compatibility of the JAVA and Gradle SDK versions by;

  • cd android -> Going back into android project.
  • java --version -> To check for java version.
  • ./gradlew --version -> to check the gradle version. Using the commands above, you may check the compatibility here

adding these lines to AndroidManifest.xml file solved this issue for me:

<meta-data
android:name="io.flutter.embedding.android.SplashScreenDrawable"
android:resource="@drawable/launch_background" />

but a warning appeared on Run console:

W/FlutterActivityAndFragmentDelegate(21657): A splash screen was provided to Flutter, but this is deprecated. See flutter.dev/go/android-splash-migration for migration steps.

I have solved this problem. If you are using flutter_splash_screen package, you should delete this package and update AndroidManifest.xml and styles.xml.
