I want to make an Android/iOS app with Flutter. I would like to create an app that can generate csv files on these actual devices and attach the csv files via email.

In the operation check on the PC, I was able to write a code that would generate a csv file. However, I generated a file on the actual device, specified where the file was on the actual device (cannot be confirmed), Can't get You can attach an email.

If i can create a file in the app's internal storage and attach the email, you can delete the file.

I'd like to create a file in the real device storage outside the app, get the path of the file, attach an email, and delete the file. Therefore, we do not know whether the file can be generated on the actual machine and where the file is generated.

I would be happy if someone could tell me.
