Is an all black barred rock possible?

The rooster isn't pure Barred Rock. He's a mixed breed.

Are melanistic chickens possible?

Yes, Silkies, & Ayam Cemani are a couple.

Are melanistic chickens possible?

The chick is just very pigmented in the face due to the Extended Black, it often fades with age.

Notice his comb
Barred rocks have single combs
Plus he has other colors on him

Oh! How can you tell?

Just noticed the rooster has a modified pea comb, not a single comb.

Your male is single barred and is a mixed breed. Your Barred Rock females are single barred because barring is sexlinked and is carried on the Z chromosome. In birds females are ZW and males are ZZ. Males receive a Z from each parent but females only receive a Z from their father. With single barring, barring is only carried on one Z making him pass a barring gene to only 50% of his offspring. With these combination of these traits, 25% of offspring would be double-barred males, 25% single barred males, 25% single barred (barred) females, and 25% black females. Your girl is the latter of the possibilities Hopefully this helps clear it up!

It looks to me like your rooster is only carrying 1 barred gene rather than the 2 barred genes a 'purebred' barred rock rooster would carry. That means he can pass on a solid gene, and all barred hens only carry 1 barred gene, so they will always pass on a solid gene to their daughters. The reason I think this is because in the photo, it looks like your rooster and hen have about the same feather pattern.
Black chicks often have very dark combs and legs, but that doesn't mean they're melanistic. As she gets closer to laying, her comb and face will get just as red as any other chicken.

Here is a photo of a barred rock rooster and a barred rock hen, where you can see how different the two should look:
