Saquon Barkley smiles as readily as Odell Beckham Jr. dances, and the news that the Giants are moving to make sure they will be Superman and Batman together, probably for the next five years at least, is making the stars shine brightly over East Rutherford, N.J.

“That’s awesome,” Barkley told The Post. “That’s awesome. I know Odell wants to be a Giant for a long time, I know how passionate he is about this organization, about this team and about the game of football, so definitely congratulations to him.”

Beckham hasn’t caught that $90 million-100 million contract just yet, but it’s in the air, and the reaction of his teammates to him not staging a holdout tells you how much potential there is for Beckham to emerge as one of Pat Shurmur’s new Giants leaders.

Listen to Landon Collins, who will be next in line for an extension:

“He loves the game. He shows that,” Collins said. “He’s not saying that he’s gonna sit out and not gonna play football because ‘I want a new contract.’ He wants to play ball, he’s playing for his teammates, he’s out here with his guys, and he loves what he does.”

The official return of Beckham to the field for the first time since fracturing his left ankle Oct. 8, flashing his rare God-given gifts of running, catching and dancing, sent a jolt of electricity through the organization.

“His game speed is ridiculous,” Barkley said — here came that smile again. “When he gets that ball in that right hand and that left hand and he opens up the strides, you could see how fast he is compared to a lot of other guys. He’s a smart player also.”

Cornerback Donte Deayon fully understands the physical and emotional road back Beckham had to travel.

“You see how hard he worked after he got injured,” Deayon said. “I was hurt around the same time, we were in the training room together rehabbing, and you just see him go through the process little by little, and now to see him back on the field, it’s exciting.”

No. 13 catches a short pass across the middle from Eli Manning. And 13 remembers what do to it.

“A lot of explosiveness,” Deayon said. “It’s good to see him back out there running around and getting his feet back under him.”

Shurmur understandably is playing it smart with Beckham. But his teammates know Beckham is akin to a caged lion, hungering to be king of the football jungle.

“He’s a competitor, and him not being out on the field last year, it probably just made him even more hungry,” Deayon said.

Beckham brings juice to the field every time. He is a kid in the candy store, frolicking on a field of dreams.

“The first thing I noticed right off the bat is he brings so much energy he picks up the entire offense,” rookie left guard Will Hernandez said. “I’ve always watched him on TV, but there’s definitely a difference when you see him actually in person. He’s explosive. He’s an incredible athlete.”

Ex-Steelers cornerback William Gay played once against Beckham, who went 10-for-100 in a 24-14 Steelers victory at Heinz Field toward the end of the 2016 season.

“He’s the same Odell that I competed against on the field as an opponent,” Gay said.

The same Odell?

“He was a dynamic receiver, somebody who we had to double cover and try to eliminate from the game,” Gay said.

When you wish upon a star as Barkley does, there is no time to be starstruck.

“I want to be just as good as him one day,” Barkley said. “I want to be just as good as Eli one day. I want to have that same impact on the offense like they have.”

Beckham and Barkley … Killer Bs together.

“On paper, it’s scary,” Gay said. “But we gotta make it come to reality.”

The Giants appear committed to making it a reality, and with good reason: They would much prefer to play with Odell Beckham Jr. than against him.
