Multiline import statements

[nvi9]

Describe the bug When an import statement being splitted in multiple lines (eg. because exceeding the default 80 characters with show or hide on any long import) the tool moves these lines to the end of the import list. It seems these import statements are not recognized, so they are put in afterImportLines here.

To Reproduce

1. For example add flutter_local_notifications as a dependency, as this package will result quite long import lines.

2. Import the package and let's say you want to hide a type (eg. because you have one with the same name in your current file already).

   import 'package:flutter_local_notifications/flutter_local_notifications.dart' hide PendingNotificationRequest;
   

3. After saving (if you have autoformat on) or formatting (eg. with dart format . or flutter format .) this line is splitted to two, since its length is 110 characters (default and recommended max line length is 80 chars).

   import 'package:flutter_local_notifications/flutter_local_notifications.dart'
       hide PendingNotificationRequest;
   

4. When running the import_sorter command, this import line "pair" is moved after all other imports.

Expected behavior Move multiline imports to the section they belong to.
