Dart how to add commas to a string number

Question

I\'m trying to adapt this: Insert commas into number string to work in dart, but no luck.

either one of these don\'t work:

print(\"1000200\".replaceAllMa         


        

Answer 1

Try the following regex: (\d{1,3})(?=(\d{3})+$)

This will provide two backreferences, and replacing your number using them like $1,$2, will add commas where they are supposed to be.
