RNDownload

Download functionality, based on react-native-background-downloader. All downloads are serial because of some issues on iOS with parallel download.

List of changes:

• Styles
• Progress event
• Network handling
• Wrapped resume functionality
• Custom download button with progress
• Whole lesson download (text, media, resources, comments)

Libraries used

• rn-fetch-blob
• react-native-svg
• @react-native-community/netinfo
