Duplicate import.

Description

#

The analyzer produces this diagnostic when an import directive is found that is the same as an import before it in the file. The second import doesn't add value and should be removed.

Example

#

The following code produces this diagnostic:

dart
import 'package:meta/meta.dart';
import 'package:meta/meta.dart';

@sealed class C {}

Common fixes

#

Remove the unnecessary import:

dart
import 'package:meta/meta.dart';

@sealed class C {}
