[Flutter] ✓ Successfully generated launcher icons , Unhandled exception: FileSystemException:...

I am getting this error when I am trying to change the app icon with the "flutter_launcher_icons 0.9.2". I tried specifing the app minsdk and targetsdk but that did not work.I have done flutter pub get several times. After that when I do:flutter pub run flutter_launcher_icons:main. I get this error

This is my pubspec.yaml:

dev_dependencies:
flutter_test:
sdk: flutter
flutter_launcher_icons: ^0.9.2

flutter_icons:
android: true
ios: true
image_path: "dev_assets/news-logos.jpeg"
adaptive_icon_background: "#FFFFFF"
adaptive_icon_foreground: "dev_assets/news-logos.jpeg"


my android/app/build.gradle:

defaultConfig {
// TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
applicationId "com.example.news_app"
minSdkVersion 21
targetSdkVersion 29
versionCode flutterVersionCode.toInteger()
versionName flutterVersionName
multiDexEnabled true
}
