What functions of WP_Filesystem allow me to create a file with code-generated contents in a directory?

I'm generating a very useful .dat file, but I read that file_put_contents if frowned upon and that WP_Filesystem should be used instead.

I see no methods to take dynamic input and create a file and then upload it to a directory of my choice at all.

What functions out of it should I look for?

My exact flow is: User clicks a button (the call is AJAX'd) and then 3 files are generated and put inside my directory. As of now, this is how the "save file" function looks like:

ob_start();
generateExprotFile();
$contents = ob_get_clean();
\file_put_contents( THEME_DIR . '/dump/test.dat', $contents );
