1777 predates the United States of America.
The 50-Star flag became the Official Flag of the United States of America by order of Executive Order #10834.
I'll point out that Owning other Humans as Slaves was also legal at one time in the United States of America, and yet times change.
I'm looking, perhaps you can help me? Can you offer anything up from the United States Federal Government, which would make the 13 Star Flag the Official United States Flag today?
