Strings are the most used objects in any language, in Dart string holds a sequence of UTF-16 code units. 2. Create a string in Dart/Flutter 2.1. Create normal strings To create a simple string in Dart/Flutter we can use either single or double quotes:
Using expressions inside a string We can put the value of an expression inside a string by using $ {expression} syntax. Dart will call the .toString () method in order to get the string corresponding to an object. When the expression is an identifier we can skip {}.
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");
