Use case

When you use an app extension with Flutter iOS apps, you'll likely want to pass information through an AppGroup. When using an AppGroup, files can be saved to a shared container between the extension and the app itself. However, you currently need to use a method channel to get the path to the container (with this API call).

Proposal

It would be great to add this to the path_provider plugin. So you can do something like the following:

Directory myFilePath = await getContainerPath("my_app_group");
