- I would prefer to store downloaded files in the app's cache directory so we have full control over it and the user can make space easily. (The following points assume this.) See Make it possible to view files without downloading them to storage #61 (comment)
- When a file gets deleted on the server, we remove the locally cached copy, e.g. when we next fetch the containing directory.
- We should provide the user with a possibility to delete the local copy.
- Even though we have a local copy, it might not be up to date → store
updatedAtfor each cached fille?

Closes: #60
Makes files available offline. When clicking on a file, it's downloaded only if necessary. Files that have already been downloaded, have an offline pin next to them:
Clicking on a downloaded file opens it. For now, files don't open automatically after they are downloaded and the pin doesn't appear when the download completed but only when revisiting the screen. Both of these limitations stem from the difficulty of detecting the finishing of a download. This can be easily resolved once the
flutter_downloaderprovides an API withFutures instead of callbacks on other isolates, which I'm working on: fluttercommunity/flutter_downloader#256
