Share A Generated File

await FileSharer.share({
  filename: 'report.pdf',
  contentType: 'application/pdf',
  base64Data: reportBase64,
  title: 'Quarterly report',
  text: 'Attached report',
});

Share A Local File

await FileSharer.share({
  filename: 'export.zip',
  contentType: 'application/zip',
  path: fileUri,
});

Save To Downloads On Android

const result = await FileSharer.save({
  filename: 'backup.zip',
  contentType: 'application/zip',
  base64Data: zipBase64,
  android: {
    saveDirectory: 'downloads',
    relativePath: 'Download/My App',
  },
});

console.log(result.uri);

Platform Notes

• Android sharing uses FileProvider, ClipData, and URI grants so chooser previews and thumbnails can read the file.
• Android saves use MediaStore on Android 10+ and public directories on Android 9 and below.
• iOS sharing supports both base64-backed temporary files and direct local path sharing.
• Web sharing and saving downloads the file, with chunked base64 conversion for large files.
