Flutter – How to dynamic access the enum

I have an enum and I want to access to it dynamically. I’m not sure if it’s possible or not.

enum EventType {
  earthquake,
  flood,
  fire
}

var event = "fire";

var mytype = EventType.event

You see, what I’m trying to achieve. Is it possible to access the enum like that (using a variable like mytype)

    Try below code

    Your Enum:

    enum EventType {
  earthquake,
  flood,
  fire
}

    Just print it:

    print( EventType.fire.name);

    Output: fire

    Other Way:

    void main() {
  const day = EventType.Fire;
  print(day.text);
}

enum EventType {
  Earthquake("earthquake"),
  Flood("flood"), 
  Fire("fire");
  

  const EventType(this.text);
  final String text;
}

    You could add this to your enum

      static EventType? fromName(String? name) {
    return values
        .firstWhereOrNull((e) => e.name == name);
  }

    then this could work:

    var event = "fire";

var mytype = EventType.fromName(event);

    Note, using firstWhereOrNull requires

    import 'package:collection/collection.dart';
