enum Style{italic, bold, underline}
Style.italic.toString() 
// print Style.italic, but I want it to be just italic

It's not currently possible to override methods of enums.

Edit: It will be possible from Dart 2.17, where the "enhanced enums" feature is planned to be released (if all goes well).

At that point, you will be able to declare methods on enum declarations, and override toString.

So, you'd be able to do:

enum Style {
  italic, bold, underline;

  @override
  String toString() => this.name; 
}

to get what you ask for. The name getter on enum values was added in Dart 2.15.

Use .name extension like MyEnum.value.name.

enum Style { italic, bold, underline }

void main(List<String> args) {
  print(Style.italic.name); // italic
}

Run on dartPad
