no_annotation_constructor_arguments
Annotation creation must have arguments.
Description
#The analyzer produces this diagnostic when an annotation consists of a single identifier, but that identifier is the name of a class rather than a variable. To create an instance of the class, the identifier must be followed by an argument list.
Example
#The following code produces this diagnostic because C is a class, and a
class can't be used as an annotation without invoking a const constructor
from the class:
dart
class C {
const C();
}
@C
var x;Common fixes
#Add the missing argument list:
dart
class C {
const C();
}
@C()
var x;
