C# enum inheritance

We can extend the enum in two orthogonal directions : we can add new methods (or computed properties), or we can add new cases. Adding new methods won’t break existing code. Adding a new case, however, will break any switch statement that doesn’t have a default case.

Enum values By default, the first member of an enum takes the value of zero. If this value doesn’t make sense for your enum, you can change it to one or some other number .

Enums are an essential part of programming languages. They help developers define a small set of predefined set of values that will be used across the logics they develop . In Dart language, which is used for developing for Flutter, Enums have limited functionality.

Extension methods, introduced in Dart 2.7, are a way to add functionality to existing libraries . You might use extension methods without even knowing it. For example, when you use code completion in an IDE, it suggests extension methods alongside regular methods.
