I am using beamer class for preparing slides for my lecture. I have some the following codes. Howe could I shift the slides numbers from right to center? I read some similar questions that have been asked in this site, but the answers of them did not work for my file.

 ‎documentclass[8pt]{beamer}‎

    ‎‎‎‎‎‎‎‎usetheme{metropolis}

    ‎‎‎setbeamercovered{transparent}‎



    ‎‎‎usepackage{ragged2e}

    usepackage{etoolbox}



    ‎usepackage{amsmath,amsthm} ‎ ‎

    ‎usepackage{mathtools}‎

    usepackage{fontspec}

    usefonttheme{serif}



    ‎newcommandFontvi{fontsize{11.2}{7.2}{{Times New Roman}}}



            ‎

    setbeamertemplate{frametitle}[default][center]

    setbeamercolor{page number in head/foot}{fg=black}

    setbeamerfont{page number in head/foot}{size=‎large‎}



    setbeamertemplate{footline}[page number]







     ‎begin{document}

     ‎

     begin{frame}frametitle{Motivations and Goals}‎

     text text text



     end{frame}‎

     ‎

     begin{frame}frametitle{Budget}

     Flowers

     end{frame}‎

     ‎

     begin{frame}frametitle{Target Values} label{targets}

    ‎$‎F=0.52‎$‎

     end{frame}



     end{document}

• If your beamer version is reasonably new, you don't need usepackage{etoolbox}




• I think the metropolis theme already loads usepackage{fontspec} for you




• In the following I centred the page number. If you want to use overlays in your presentation, you might want to replace totalpagenumber with totalframenumber
