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

another variant, how it might be solved:

enum MyEnum {
  value1,
  value2,
}

extension MyEnumX on MyEnum {
  String get asString {
    switch (this) {
      case MyEnum.value1:
        return _keyValue1;
      case MyEnum.value2:
        return _keyValue2;
    }
    throw Exception("unsupported type");
  }

  MyEnum fromString(String string) {
    switch (string) {
      case _keyValue1:
        return MyEnum.value1;
      case _keyValue2:
        return MyEnum.value2;
    }
    throw Exception("unsupported type");
  }
}

const String _keyValue1 = "value1";
const String _keyValue2 = "value2";

void main() {
    String string = MyEnum.value1.asString;
    MyEnum myEnum = MyEnum.value1.fromString(string);
}
