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

I think my approach is slightly different, but might be more convenient in some cases. Finally, we have parse and tryParse for enum types:

import 'dart:mirrors';

class Enum {
  static T parse(String value) {
    final T result = (reflectType(T) as ClassMirror).getField(#values)
        .reflectee.firstWhere((v)=>v.toString().split('.').last.toLowerCase() == value.toLowerCase()) as T;
    return result;
  }

  static T tryParse(String value, { T defaultValue }) {
    T result = defaultValue;
    try {
      result = parse(value);
    } catch(e){
      print(e);
    }
    return result;
  }
}

EDIT: this approach is NOT working in the Flutter applications, by default mirrors are blocked in the Flutter because it causes the generated packages to be very large.
