Steps to Reproduce

when

config.sessionReplayConfig.maskAllTexts = true;
config.sessionReplayConfig.maskAllImages = true;

https://github.com/PostHog/posthog-flutter/blob/main/lib/src/replay/screenshot/screenshot_capturer.dart#L101-L103

Uint8List pngBytes = byteData.buffer.asUint8List();
image.dispose(); // <-----

image dispose but it still used in

        if (screenElementsRects != null) {
          final ui.Image maskedImage = await _imageMaskPainter.drawMaskedImage(
              image, screenElementsRects, pixelRatio);
          final imageInfo = ImageInfo(
              maskedImage,
              viewId,
              globalPosition.dx.toInt(),
              globalPosition.dy.toInt(),
              srcWidth.toInt(),
              srcHeight.toInt(),
              shouldSendMetaEvent,
              pngBytes);
          _updateStatusView(shouldSendMetaEvent, renderObject, statusView);
          return imageInfo;
        }
