saveToPath configuration for MacOs
saveToPath function by default saves file in ~/Documents/file_picker_cross folder, until application sandbox is enabled. This folder is exposed to user, and can be modified by multiple flutter applications.
According to guidelines we have to use LibraryDirectory, ApplicationSupportDirectory or DocumentDirectory for different kinds of data. May be configuration of root for saveToPath should be added?
Or at least application name should be used instead of file_picker_cross, when we store in ~/Documents
