library_ annotations
This annotation should be attached to a library directive.
Description
#
The analyzer produces this diagnostic when an annotation that applies to
a whole library isn't associated with a
library
directive.
Example
#
The following code produces this diagnostic because the
TestOn
annotation, which applies to the whole library, is associated with an
import
directive rather than a
library
directive:
@TestOn('browser')
import 'package:test/test.dart';
void main() {}
Common fixes
#
Associate the annotation with a
library
directive, adding one if
necessary:
@TestOn('browser')
library;
import 'package:test/test.dart';
void main() {}
