Butland, 19, stepped in for the friendly against Italy last month and also starred for Team GB at the Olympics.
The Birmingham City star earned rave reviews from mentor Hart.
City stopper Hart said: "Jack's a great young keeper, I spoke to him throughout Euro 2012 and during the Olympics.
"He's a great prospect but he just needs to play now. To play in the Olympics at 19 is a great experience for him. He's got a massive future at the top."
