duplicate_export
Duplicate export.
Description
#The analyzer produces this diagnostic when an export directive is found that is the same as an export before it in the file. The second export doesn't add value and should be removed.
Example
#The following code produces this diagnostic because the same library is being exported twice:
dart
export 'package:meta/meta.dart';
export 'package:meta/meta.dart';
Common fixes
#Remove the unnecessary export:
dart
export 'package:meta/meta.dart';
