Flutter/Dart Enums & Extension

How Enums and Extension work in every framework to maintain and write easy code.

Understating Enums:

enum DeviceName{ Apple, Nokia }

print(DeviceName.Apple.toString()) -> DeviceName.Apple : That's mean your full enum class 
values will be printed as string.

print(DeviceName.Apple.name) -> Apple : It will only print your name enum value as string. //Best practice

So before comparing, assigning keep in mind what the actual value your are using.


Or you can use extension 

##Declare Enums
enum UserType{ bot, doctor, patient }


##String to Enum

extension UserType on String {
 Topic get topic {
   switch (this) {
     case 'bot':
       return UserType.bot;
     case 'doctor':
       return UserType.doctor;
     case 'patient':
       return UserType.patient;
   }
 }
}


## Enum to string 
extension UserTypeExtension on UserType {
 String get string {
   switch (this) {
     case UserType.bot:
       return 'bot';
     case UserType.doctor:
       return 'doctor';
     case UserType.patient:
       return 'patient';
   }
 }
}
