how to write under leftright arrow

Question

I have question please about writing under arrows

I know $\overleftarrow{A}$ draw a directed arrow to the left, similarly $\overrightarrow{A}$ draws a directed arrow to the right, but I can't find a command like $\overarrow{A}$ to draw left-right arrow.

Anyone can help me in this!

Without any extra package: $\stackrel{A}{\leftrightarrow}$

With amsmath: $\underleftrightarrow{A}$

Do you mean this?

\documentclass[12pt, letterpaper]{article}
\usepackage{mathtools}
\begin{document}
This is for test $\xleftrightarrow{A}$
\end{document}

There is also a useless package called halloweenmath to write underleftright arrow. Here there is a table where you can see that the lenght of the arrow is the same of the character.

\documentclass[a4paper,12pt]{article}
\usepackage{halloweenmath}
\usepackage{booktabs}
\begin{document}
Your desidered code: $\underscriptleftrightarrow{A}$.
\begin{table}[h]
\begin{tabular}{@{}|l|l|@{}}
\toprule
$\overscriptleftarrow{A}$      & $\underscriptleftarrow{A}$      \ \midrule
$\overscriptleftrightarrow{A}$ & $\underscriptleftrightarrow{A}$ \ \midrule
$\overscriptrightarrow{A}$     & $\underscriptrightarrow{A}$     \ \bottomrule
\end{tabular}
\end{table}
\end{document}
