I was coaching a high school rules girls game in NY State this past weekend. B1 fouled A1 who was shooting a field goal attempt.The shot did not go in. Referee called a flagrant foul on B1 and awarded 4 free throws plus the ball(back to team A). I only expected 2 free throws. I missed the exact call because I was tending to a player's injury on my bench.
Was the refree correct to award FOUR free throws under any situation like this? I asked the ref who did not make the call if it was a flagrant Technical foul and he said "yes".

Does a flagrant Technical on a shooting foul (with FG attempt missing) result in 4 free throws?

(The ref awarded 4 free throws on a similair play later in the game too.)
