Sample code hang when using save button

[Nimo11]

Sample code hang when trying to save.

There is no bytes when calling save method.

Future _saveFile() async {
_resetState();
try {
String? fileName = await FilePicker.platform.saveFile(
allowedExtensions: (_extension?.isNotEmpty ?? false) ? _extension?.replaceAll(' ', '').split(',') : null,
type: _pickingType,
dialogTitle: _dialogTitleController.text,
fileName: _defaultFileNameController.text,
initialDirectory: _initialDirectoryController.text,
lockParentWindow: _lockParentWindow,
bytes: Uint8List(100)); <-- missing paramters

Thanks for your job
