Action

• Action contains two fields
  • type
  • payload
• Recommended way of writing action
  • Create an action.dart file for a component|adapter that contains two classes
    • An enumeration class for the type field
    • An ActionCreator class is created for the creator of the Action, which helps to constrain the type of payload.
  • Effect Accepted Action which's type is named after on{verb}
  • Reducer Accepted Action which's type is named after {verb}
  • Sample code

enum MessageAction {
    onShare,
    shared,
}

class MessageActionCreator {
    static Action onShare(Map<String, Object> payload) {
        return Action(MessageAction.onShare, payload: payload);
    }

    static Action shared() {
        return const Action(MessageAction.shared);
    }
}
