invalid_literal_annotation
Only const constructors can have the @literal
annotation.
Description
#The analyzer produces this diagnostic when the literal
annotation is applied to anything other than a const constructor.
Examples
#The following code produces this diagnostic because the constructor isn't a const
constructor:
import 'package:meta/meta.dart';
class C {
@literal
C();
}
The following code produces this diagnostic because x
isn't a constructor:
import 'package:meta/meta.dart';
@literal
var x;
Common fixes
#If the annotation is on a constructor and the constructor should always be invoked with const
, when possible, then mark the constructor with the const
keyword:
import 'package:meta/meta.dart';
class C {
@literal
const C();
}
If the constructor can't be marked as const
, then remove the annotation.
If the annotation is on anything other than a constructor, then remove the annotation:
var x;
