Hi @codermonk1, @sunqihui222, did the solution provided by maplerder work for you? as mentioned in the StackOverflow post, manageExternalStorage is a risky permission where you have to fill in a form if you want to publish the app. the link to the form can be found at the Permission.manageExternalStorage permissions documentation.

When using the Date & Time as part of the file name, do not include the semicolon(:) in the time field. You must remove the semicolon and change it to a hyphen (-)

'/storage/emulated/0/New Project/v_2022-09-24 16-17-52.109373'

you should use or create the folder inside the system folder which is created by android

for example you create folder name xyz then you should create this folder inside DCIM folder or in PICTURE folder ... any system folder... for exam code.. createFolder() async { PermissionStatus permissionResult = await Permission.storage.request(); if (permissionResult == PermissionStatus.granted) { new Directory('/storage/emulated/0/DCIM/(your folder name)') .create() // The created directory is returned as a Future. .then((Directory directory) {}); } }

ok i will try this

hi , did you find the solution ?, here is my case

var status = await Permission .storage .status;
if (!status.isGranted || await Permission.manageExternalStorage.request().isDenied) {
  await Permission .storage .request();
}

the i create a path like this

return File("/storage/emulated/0/Download/$filename");

after that i write to that storage loaction

await viewFile?.writeAsBytes(bytes);

i receive file as bytes, so its working file in most of the phones , got error in motog40 fusion, android version 12

i found the solution changing this way

Future getStoragePermission() async {
  PermissionStatus status = await Permission.storage.request();
  //PermissionStatus status1 = await Permission.accessMediaLocation.request();
  PermissionStatus status2 = await Permission.manageExternalStorage.request();
  print('status $status   -> $status2');
  if (status.isGranted && status2.isGranted) {
    return true;
  } else if (status.isPermanentlyDenied || status2.isPermanentlyDenied) {
    await openAppSettings();
  } else if (status.isDenied) {
    print('Permission Denied');
  }
}

When using the Date & Time as part of the file name, do not include the semicolon(:) in the time field. You must remove the semicolon and change it to a hyphen (-)

Example: 
'/storage/emulated/0/New Project/v_2022-09-24 16-17-52.109373'

its worked for me thank u so much made my day

Thank you @codermonk1 for opening this question. It appears that many people are wondering the same thing.

Thanks to everyone weighing in on the conversation. I feel like the question has been addressed sufficiently. The error is caused by an issue with creating the file, such as an invalid file name or a directory that the application is not allowed to access.

Future readers can look into this conversation to help them resolve their issues, or search online for help with writing files in Android.
