You can't access to External storage in ios directly according to the guidelines for security purposes. However, you could access NSDocumentDirectory through path_provider package to do that. But you would only be able to access it within the app. So it might not fulfil the usecase of exporting the csv directly.
I was taking a look at some of the issues to pick. Let me know if you have any other solution

Is it possible to generate export files and attach them to the MFMailComposeViewController, so the user could send them to himself?

yeah, that's a good way. will raise a PR
