The 38-year-old, minding the Oakwell shop after the sacking of his former mentor Keith Hill, guided the Tykes to a victory that was more resounding than it appeared, with Chris Dagnall's brace doing the trick.
Flitcroft has now overseen two wins out of two, all while the likes of Terry Butcher and Sean O'Driscoll have turned down the vacant job.
An announcement from Barnsley on Hill's permanent successor is still to come, and Flitcroft did his best at flat-batting talk he is the main man afterwards. He did, however, reveal that if he is offered the job, he will not be turning it down.
"I have found out a lot about myself in the last 10 days. It could change the way I look at myself for the rest of my career," he said. "When you lead a group and they are all playing for you, it's different. I'm not going to walk out on that group of players.
"If I get sacked, I get sacked, but I've been taught well and you don't walk out on people."
Leeds have lost 5-2, 4-1 and 2-0 on their last three visits to Barnsley - albeit two of them under Simon Grayson - and Neil Warnock felt the wrath of the 5,000 travelling supporters.
He tried to placate them by bringing a laptop to his post-match press conference and showing an incident he thought should have earned Barnsley's Stephen Dawson a red card - a foul on Ross McCormack - but did admit his men were not up to the job.
"We were very poor in the first half and if I had have been one of the 5,000 I might have said what they were," he conceded.
"I thought we had some great chances at the start of the second half and then there was a horrendous tackle from Dawson. How that's not a red card I don't know."
