compress static method

Future<File?> compress({ required File image, CompressParams compressParams = defaultCompress, })

Converts HEIC/WebP/PNG to JPEG when CompressParams.format is CompressFormat.jpeg and applies optional resize. Uses EXIF-based orientation when autoCorrectionAngle is true.

Implementation

static Future<File?> compress({
  required File image,
  CompressParams compressParams = defaultCompress,
}) async {
  final dir = await getTemporaryDirectory();
  final ext = switch (compressParams.format) {
    CompressFormat.jpeg => 'jpg',
    CompressFormat.png => 'png',
    CompressFormat.heic => 'heic',
    CompressFormat.webp => 'webp',
  };
  final targetPath = '${dir.path}/compressed_${DateTime.now().millisecondsSinceEpoch}.$ext';

  final compressedFile = await FlutterImageCompress.compressAndGetFile(
    image.absolute.path,
    targetPath,
    quality: compressParams.quality,
    minHeight: compressParams.targetHeight,
    minWidth: compressParams.targetWidth,
    autoCorrectionAngle: compressParams.autoCorrectionAngle,
    format: compressParams.format,
    keepExif: compressParams.keepExif,
  );

  if (compressedFile == null) {
    debugPrint('Compression failed');
    return null;
  }

  return File(compressedFile.path);
}
