'Window_sendPlatformMessage' (4 arguments) cannot be found #26413
Description
I am developing an app with Flutter that takes an image and allows the user to save it in the gallery.
I am using image_picker_saver plugin to save it.
In the beginning I was calling the method to save the image in the main thread but I realized that was really slow and now I am trying to put it in a new isolated thread, but I am getting the same error all the time.
Run flutter doctor -v

compute(saveImage, _imageFile).then((Future<String> futurePath) {
futurePath.then((String path){

.
}
toCompute.dart
Future<String> saveImage(File image) async {
return await ImagePickerSaver.saveFile(fileData: image.readAsBytesSync());
}I tried to change the code trying to locate the error but is always the same:

Thanks in advance!
