What happened?

Hello,

I've been using your package and encountered a specific problem when excluding directories in pubspec.yaml for FlutterGen. This issue involves handling filenames with special characters, such as a plus sign (+), which aren't processed correctly despite being in an excluded directory.

Configuration:

flutter_gen:
  output: lib/assets/
  assets:
    outputs:
      class_name: MyAssets
    exclude:
      - assets-extern/

Problem: Despite excluding the assets-extern/directory, FlutterGen processes files from this directory, leading to a build error:

Operator declarations must be preceded by the keyword 'operator'.
AssetGenImage get myasset+ffffff => const AssetGenImage('assets-extern/myasset+_fffff.jpg');

It seems, that FlutterGen is parsing first everything and then applying a filter with the declared excluded paths. I understand this is a very special case due to the unique filenames connected to our database models. However, I confirmed the build runner recognizes this configuration. Is there a possible solution to handle filenames with special characters?

Thank you!

Relevant a pubspec.yaml.

flutter_gen:
  output: lib/assets/ 

  assets:
    outputs:
      class_name: MyAssets

    exclude:
      - assets-extern/

Relevant log output

Operator declarations must be preceded by the keyword 'operator'.

        AssetGenImage get myasset+ffffff => const AssetGenImage('assets-extern/myasset+_fffff.jpg');

I'm not seeing the behavior with v5.5.0. Could you confirm the issue persists? I've also checked the implementation, it seems that the exclude section uses Glob to parse entries, which assets-extern/* is a valid key in this case.
