[FeatureRequest] Prevent models from adding to the "export" section of "index.dart"

[greyovo]

Problem

Sometimes, a field in a JSON file is an object, and the name of this key may also appear in other JSON.

It's no problem when importing files separately, but the current practice will automatically add the generated classes to the "export" statement in the "index.dart" file, resulting in naming conflicts.

Solution

Provide an option to prevent the generated model class from being automatically added to the "export" section of "index.dart".
