How to insert characters into a Dart String?

Question

I would like to add some white spaces to a Dart String in a given position, exactly like this (In Java).

so...

'XPTOXXSFXBAC' become 'XPTO XXSF XBAC'

Is there an easy way?

Answer 1

You can use the replaceAllMapped method from String, you have to add the regular expression, like this:

 final value =  "XPTOXXSFXBAC".replaceAllMapped(RegExp(r".{4}"), (match) => "${match.group(0)} ");
 print("value: $value");
