saveMultipleFiles method

@override Future<List<String>> saveMultipleFiles({ required List<Uint8List> dataList, required List<String> fileNameList, required List<String> mimeTypeList, })

Saves multiple files using platform-specific implementation.

Returns a list of saved file paths (or identifiers) for each file. On iOS the paths are temporary staging locations; on Web they indicate that a browser download was triggered.

dataList: List of file data in bytes. fileNameList: List of file names with extensions. mimeTypeList: List of corresponding MIME types.

Implementation

@override
Future<List<String>> saveMultipleFiles({
  required List<Uint8List> dataList,
  required List<String> fileNameList,
  required List<String> mimeTypeList,
}) async {
  final downloadsDir = await getDownloadsDirectory();
  if (downloadsDir == null) {
    throw StateError('Could not locate the Downloads directory.');
  }

  final results = <String>[];

  for (int i = 0; i < dataList.length; i++) {
    final file = File(
      '${downloadsDir.path}${Platform.pathSeparator}${fileNameList[i]}',
    );
    await file.writeAsBytes(dataList[i], flush: true);
    results.add(file.path);
  }

  return results;
}
