Future<void> overwriteExistingIcons(
  AndroidIconTemplate template,
  Image image,
  String filename,
  String? flavor,
) async {
  final Image newFile = utils.createResizedImage(template.size, image);
  final pngFile = await File(
    constants.androidResFolder(flavor) +
        template.directoryName +
        '/' +
        filename,
  ).create(recursive: true);
  await pngFile.writeAsBytes(encodePng(newFile));
}
