Enum from String

Question

I have an Enum and a function to create it from a String because i couldn\'t find a built in way to do it

Answer 1

Your enum

enum Day {
  monday,
  tuesday,
}

Add this extension (need a import 'package:flutter/foundation.dart';)

extension EnumEx on String {
  Day toEnum() => Day.values.firstWhere((d) => describeEnum(d) == toLowerCase());
}

Usage:

void main() {
  String s = 'monday'; // String
  Day monday = s.toEnum(); // Converted to enum
}
