Remove describeEnum
The `describeEnum` method has been removed from the Flutter framework. Since Dart 2.14, enums have a `name` getter that does the same thing.
Summary
#
The describeEnum method has been removed from the framework because it's redundant with the
name
getter on Enum which was introduced in Dart 2.14.
Context
#
Historically, Flutter used describeEnum to return a String description of an enum value.
This became redundant when the name getter of Enum was introduced in
Dart 2.14.
Migration guide
#
If your code previously used the describeEnum method to get the value name of an enum member,
migrate your code to use the name getter on the instance itself.
enum Theme { light, dark }
final theme = describeEnum(Theme.light);
Theme.light.name;
