writeFile method

Future<FileInfo> writeFile({ required String identifier, String fileName = 'temp', required Future<void> writer(File file), })

Writes data to a file previously picked by the user. Expects a FileInfo.identifier string for identifier. The writer will receive a file in a temporary directory named fileName (if not given will be called temp). The temporary directory will be deleted when writing is complete.

Implementation

Future<FileInfo> writeFile({
  required String identifier,
  String fileName = 'temp',
  required Future<void> Function(File file) writer,
}) async {
  _logger.finest('writeFileWithIdentifier()');
  final result =
      await _createFileInNewTempDirectory(fileName, (tempFile) async {
    await writer(tempFile);
    final result = await _channel
        .invokeMapMethod<String, String>('writeFileWithIdentifier', {
      'identifier': identifier,
      'path': tempFile.absolute.path,
    });
    return result!;
  });
  return _resultToFileInfo(result);
}
