[Tex/LaTex] How to create a negated arrow on \xRightarrow

arrowsmath-mode

Similar to this question, but with the \xRightarrow instead. I tried changing the 3rd version to use \Rightarrow like so:

\documentclass{standalone}

\usepackage{amsmath}
\usepackage{amssymb} % for \diagup
\usepackage{mathtools}
\usepackage{tikz} % for tikz solution

\makeatletter
\def\slashedarrowfill@#1#2#3#4#5{%
  $\m@th\thickmuskip0mu\medmuskip\thickmuskip\thinmuskip\thickmuskip
   \relax#5#1\mkern-7mu%
   \cleaders\hbox{$#5\mkern-2mu#2\mkern-2mu$}\hfill
   \mathclap{#3}\mathclap{#2}%
   \cleaders\hbox{$#5\mkern-2mu#2\mkern-2mu$}\hfill
   \mkern-7mu#4$%
}

\def\rightslashedarrowfillc@{%
  \slashedarrowfill@\relbar\relbar{\raisebox{.12em}{\tiny/}}\Rightarrow}
\newcommand\xslashedrightarrowc[2][]{%
  \ext@arrow 0055{\rightslashedarrowfillc@}{#1}{#2}}
\makeatother

\begin{document}
    A \xslashedrightarrowc{abcdefg} C\\[12pt]
\end{document}

But I end up with this instead:

slashed arrows again

I'm assuming something's wrong with the def of \slashedarrowfill but I don't know enough to fix it. Could someone point me in the right direction please?

Heiko Oberdiek's centernot package comes in handy for that:

enter image description here

\documentclass{standalone}

\usepackage{centernot}
\usepackage{mathtools}

\begin{document}
$\centernot{\xRightarrow{sdfkjhsdf}}$
\end{document}
