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 of goals doing the trick.
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.
"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."
Press Association Sport understands Barnsley could make a decision by Sunday and, regardless of who gets the job, Flitcroft was happy with what his men produced in what could prove to be his final game as a caretaker.
"As a coach, you look at the performance. I told them at half-time I was excited about it. We over-ran and dominated Leeds," he said.
"I wanted to spend some time with the players and celebrate with them after the game, especially someone like Chris Dagnall. I worked with him at Rochdale where he got 24 in a season for us.
"I picked some music and put the goals to it and showed him before kick-off. He epitomises what it's like to be a Barnsley fan. He's hard working and he has that ethic they want."
