Key Features #
Ready to Use #
The AssetDownloader includes a CachedAssetWidget, making it straightforward to integrate by simply passing the URL of the desired file.
Manual Pre-Downloads #
Enables manual queuing of pre-downloads, allowing the application to fetch assets in advance for future use.
Use the enqueueDownloadTask method exposed by the AssetDownloader.
Auto-Deletion of Unused Files #
To prevent unnecessary storage clutter, the plugin includes a cleanup mechanism that automatically deletes unused files.
Configurable Stale Period and Capacity #
During initialization, users can specify the total allowed stale period. If a file remains untouched for this duration, it is flagged for deletion during the cleanup process.
The configuration also includes setting the total capacity, defining the total number of downloads allowed. If there are more downloaded files than the specified capacity, the least recently used files will be removed.
