[An19ik89]

Can you help me with one thing i don't understand how to do that.Please i am grateful to you if you help me.
PhotoFilter _photoFilter;
Filter _filter = presetFiltersList[23];
_photoFilter = new PhotoFilter(
image: image,
filename: fileName,
filter: _filter,
fit: BoxFit.fill,
);
After doing that I need the filtered image.
Uint32List _uint32list = _photoFilter.image.data;
Uint8List byte_data= _uint32list.buffer.asUint8List(); i did that process to get the filtered image.but could not. wheni try to read the filtered image in Image.memory(byte_data);
showing that "Exception: Invalid image data"
can you help me please ?

I hope this will help you

void applyFilterOnFile(Filter filter, String src, String dest) {
  Image image = decodeImage(File(src).readAsBytesSync());
  var pixels = image.getBytes();
  filter.apply(pixels, image.width, image.height);
  Image out = Image.fromBytes(image.width, image.height, pixels);
  new File(dest).writeAsBytesSync(encodeNamedImage(out, dest));
}

I also face this problem

TO solve this problem I simply edit library.
In library there was get path of WRONG directory
replace with
dirctory = getTempraryDirectories();
in side the library
