flutter_network_file_manager #

A FileManager for files from the network and store them in the directory of the app to later use offline. Unlike caching, this manager stores the files in a private directory. This way the files will only be deleted when the application itself is deleted.

The files are tracked by their url and optionaly by a given name and/or a timestamp. When the url or timestamp are changed, the old file will be removed and a new version will be downloaded.

0.0.1 #

  • TODO: Describe initial release.

Maintenance issues and suggestions

Support latest dependencies. (-10 points)

The version constraint in pubspec.yaml does not support the latest published versions for 1 dependency (path_provider).

The package description is too short. (-20 points)

Add more detail to the description field of pubspec.yaml. Use 60 to 180 characters to describe the package, what it does, and its target use case.

Package is pre-v0.1 release. (-10 points)

While nothing is inherently wrong with versions of 0.0.*, it might mean that the author is still experimenting with the general direction of the API.
