FileUploader

FileUploader(__namedParameters): Element

Defined in: src/components/controls/FileUploader/FileUploader.tsx:105

Drag-and-drop file uploader with click-to-browse fallback. Renders a list of uploaded items with per-file status (pending / uploading / done / error) and an animated progress bar.

The component itself is purely presentational around the file list — it does not perform the actual upload. The consumer is expected to:

1. Listen to onFilesAdd (or onChange) to know which files were accepted by the uploader.
2. Drive the upload (fetch / XHR / SDK) externally.
3. Reflect progress back into the component by passing a controlled value and updating the status / progress of each item.
