abstract_field_initializer
Abstract fields can't have initializers.
Description
#The analyzer produces this diagnostic when a field that has the abstract
modifier also has an initializer.
Examples
#The following code produces this diagnostic because f
is marked as abstract
and has an initializer:
abstract class C {
abstract int f = 0;
}
The following code produces this diagnostic because f
is marked as abstract
and there's an initializer in the constructor:
abstract class C {
abstract int f;
C() : f = 0;
}
Common fixes
#If the field must be abstract, then remove the initializer:
abstract class C {
abstract int f;
}
If the field isn't required to be abstract, then remove the keyword:
abstract class C {
int f = 0;
}
