In your build.gradle file, inside your android block you are compiling and targeting API level 34:
android {
namespace "com.coherents.Project"
compileSdkVersion 34 // <---- HERE
ndkVersion "27.0.12077973"
....
defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.coherents.Project"
// You can update the following values to match your application needs.
// For more information, see: https://docs.flutter.dev/deployment/android#reviewing-the-gradle-build-configuration.
minSdkVersion 24
targetSdkVersion 34 // <--- HERE
...
}
}
but the attribute windowOptOutEdgeToEdgeEnforcement was only added in API level 35.
So you need to at least change your compileSdkVersion to API level to 35.
