getImageDimensions method

Implementation

@override
Future<ImageDimensions> getImageDimensions(Uint8List imageBytes) async {
  final blob = Blob([imageBytes]);
  final imageUrl = Url.createObjectUrlFromBlob(blob);

  final image = ImageElement();
  image.src = imageUrl;

  try {
    // Wait for the image to load / render
    await image.onLoad.first;

    int? width = image.width;
    int? height = image.height;

    if (width == null || height == null) {
      throw ("Width or height is null. Width: $width; Height: $height");
    }

    // Create the image dimensions object and return it
    return ImageDimensions(width, height);
  } catch (e) {
    rethrow;
  }
