android file export error

[lopallo]

Hello, on Android with version 0.1.1 I had no problem to export a file, but using version 0.2.8 I get this error:
D/FileSaver( 5086): Error While Calling methodNo Activity found to handle Intent { act=android.intent.action.CREATE_DOCUMENT cat=[android.intent.category.OPENABLE] flg=0xc3 (has extras) }

Which android version and can you possibly share a code block?

I verified with Nexus 5Xapi30 emulator and with smartphone with Android 13

Future exportTurni() async {
String esporta = await dbTurni.exportDbTurni();
final directory = await getApplicationDocumentsDirectory();
final path = directory.path;
File file = File('$path/turni_mensili.json');
await file.writeAsString(esporta);
//controlla se il file è stato effettivamente esportato
if (file.existsSync()) {
//esporta il file
Uint8List bytes = file.readAsBytesSync();
FileSaver.instance.saveAs('turniMensili', bytes, 'json', MimeType.JSON);
} else {
//mostra un messaggio di errore
ScaffoldMessenger.of(context).showSnackBar(
const SnackBar(
content: Text(
'Errore durante l'esportazione del file',
),
),
);
}
}
}
