Error removing page from pdf #1246
Description
The pdf file I get from a webpage starts with a blank page, which I want to remove before writing the file, but removing a page from PdfDocument throws an exception.
I tried it like this:
`final path = Constants.filePath;
final PdfDocument document = PdfDocument(inputBytes: response.bodyBytes);
int count = document.pages.count; //8
final page = document.pages[0]; //works
document.pages.remove(page); //exception occurs here, removeAt() doesn't work either
File file = File(path);
file.writeAsBytesSync(document.saveSync());
document.dispose();`
This is the exception:
Unhandled Exception: Null check operator used on a null value

Does anyone know how to solve this?
