saveAs method

Future<String?> saveAs({ required String name, Uint8List? bytes, File? file, String? filePath, LinkDetails? link, required String ext, required MimeType mimeType, String? customMimeType, Dio? dioClient, Uint8List transformDioResponse(dynamic data)?, })

saveAs This method will open a Save As File dialog where user can select the location for saving file.

name: Name of your file.

bytes: Encoded File for saving Or file: File to be saved. Or filePath: Path of file to be saved. Or link: Link of file to be saved. LinkDetails is a model which contains link & headers LinkDetails( link: 'https://www.google.com', headers: { 'your-header': 'header-value', }, ),

Out of these 4 parameters, only one is required.

ext: Extension of file.

mimeType (Mainly required for web): MimeType from enum MimeType..
