Toggle auto-indenting for code paste in vim

Pasting text into a terminal running Vim with ‘autoindent’ or ’smartindent’ set can destroy the indenting of the pasted text.

How to solve this problem?

Before paste

:set paste

After paste

:set nopaste

Or we can just add this in .vimrc config file, so that we can make a toggle for this action.

set pastetoggle=<F9>
