enum_with_abstract_member
'{0}' must have a method body because '{1}' is an enum.
Description
#The analyzer produces this diagnostic when a member of an enum is found that doesn't have a concrete implementation. Enums aren't allowed to contain abstract members.
Example
#The following code produces this diagnostic because m
is an abstract method and E
is an enum:
dart
enum E {
e;
void m();
}
Common fixes
#Provide an implementation for the member:
dart
enum E {
e;
void m() {}
}
