找到答案，你可以使用dart:io，我也使用了Permissions_handler

Future exportReport() async {
var excel = Excel.createExcel();
DateTime _now = DateTime.now();
String _name = DateFormat('yyyy-MM-dd').format(_now);
String _fileName = 'surname-' + _name;
List<int>? potato = excel.save(fileName: _name);
PermissionStatus status = await Permission.storage.request();
if (status == PermissionStatus.granted) {
await File('/storage/emulated/0/Download/$_fileName.xlsx').writeAsBytes(potato!, flush: true).then((value) {
log('saved');
});
} else if (status == PermissionStatus.denied) {
log('Denied. Show a dialog with a reason and again ask for the permission.');
} else if (status == PermissionStatus.permanentlyDenied) {
log('Take the user to the settings page.');
}
return null;
}
