Hide central characters of an email address in Dart – Flutter

Given an email-string as below

String email = "[email protected]"

I’d like to show in my Flutter code a censored string, e.g:

"na******[email protected]"

I tried email.replaceRange(2, email.length, "*" * (email.length - 2)) with output:

"na******************"

I’d like to stop the censorship before @, maybe 2 or 3 characters before.

    String email="[email protected]";
var nameuser = email.split("@");
var emailcaracter=email.replaceRange(2,nameuser[0].length,"*" * (nameuser[0].length-2));
print(emailcaracter);

    result :

    de*******@gmail.com

    You can use this method to achieve what you want exactly:

    String unconsore(String string, {int consoreLevel = 2}) {
  final parts = string.split("@");

  if (parts.length != 2) {
    // Handle the case where there is no "@" separator in the string
    return string;
  }

  final stringBeforeA = parts[0];
  final stringAfterA = parts[1];

  final unconsoredBeforeA = stringBeforeA.replaceRange(
      consoreLevel, stringBeforeA.length - consoreLevel, "*" * (stringBeforeA.length - consoreLevel * 2));

  return "$unconsoredBeforeA@$stringAfterA";
}

// example
print(unconsore("[email protected]")); // na*******[email protected]
