overwriteDefaultIcons function

void overwriteDefaultIcons(
  1. IosIconTemplate template,
  2. Image image, [
  3. String iconNameSuffix = ''

Implementation

void overwriteDefaultIcons(IosIconTemplate template, Image image, [String iconNameSuffix = '']) {
  final Image newFile = createResizedImage(template, image);
  File(iosDefaultIconFolder + iosDefaultIconName + iconNameSuffix + template.name + '.png')
    ..writeAsBytesSync(encodePng(newFile));
}
