I am using below code to access gallery permissions in .net maui but it always returns Granted even on first time launch of the application and I am not able to see the permission popup saying "This app would like to access photos and media on your device"
public static async Task<PermissionStatus> GetMediaPermissionStatus()
{
PermissionStatus mediaResult = PermissionStatus.Disabled;
var tcs = new TaskCompletionSource<PermissionStatus>();
var status = await Permissions.CheckStatusAsync<Permissions.Photos>();
if (status != PermissionStatus.Granted)
{
status = await Permissions.RequestAsync<Permissions.Photos>();
}
tcs.SetResult(status);
return await tcs.Task;
}
Also when I execute below code getting 2 app permission Popups
1st Popup - "Allow application to take pictures and record video"
2nd Popup - "Allow application to access photos and media on your device?"
public async void TakePhoto()
{
if (MediaPicker.Default.IsCaptureSupported)
{
FileResult photo = await Microsoft.Maui.Media.MediaPicker.Default.CapturePhotoAsync();
if (photo != null)
{
// save the file into local storage
string localFilePath = Path.Combine(FileSystem.CacheDirectory, photo.FileName);
using Stream sourceStream = await photo.OpenReadAsync();
using FileStream localFileStream = File.OpenWrite(localFilePath);
await sourceStream.CopyToAsync(localFileStream);
}
}
}
I don't know if it is a bug or I am doing something wrong.
Any help is appreciated!
You can refer to this doc: Permissions of MAUI. There is a table in it. It uses ✔️ to indicate that the permission is supported and ❌ to indicate the permission isn't supported or isn't required
If a permission is marked as ❌, it will always return Granted when checked or requested.
Granted:
The user granted permission or is automatically granted.
Wish it can help you.

I want to ask user to enable permission only if he denied the permission or the permission is not allowed
This function is working very well on android
Future _getLocationPermission() async {
if (await Permission.location.request().isGranted) {
permissionGranted = true;
} else if (await Permission.location.request().isPermanentlyDenied) {
throw('location.request().isPermanentlyDenied');
} else if (await Permission.location.request().isDenied) {
throw('location.request().isDenied');
permissionGranted = false;
}
}
but on iOS it throw exception permission isPermanentlyDenied
Unhandled Exception: location.request().isPermanentlyDenied
even if the user allowed location permission while using app
I'm using permission_handler package
iOS is stricter, it does not allow you to request for permission if the user has already permanently denied it. In this case your only option is to inform the user about this, and offer the possibility to open application settings and grant permission there. This will likely restart your application if the user grants.
So check the status without requesting:
final status = await Permission.location.status;
If status is permanently denied, display a Flutter dialog (you can't use the system permission grant dialog in this case):
if (status == PermissionStatus.permanentlyDenied) {
// display a dialog, explain the user that he/she can grant
// permission only in the phone's application settings
}
If the user want's to do it, you can route to the application settings:
openAppSettings(); // this is a method of the permission handler package
This method is a future, but in my experience you don't need to await it.
This is just a function that returns bool if the user enables location
or not simple
Future<bool> canGetLocation(Location location) async {
if (!await location.requestService()) return false;
final status = await location.requestPermission();
final granted = PermissionStatus.granted;
final grantedLimited = PermissionStatus.grantedLimited;
bool result = status == granted || status == granted;
return result;
}
if (await canGetLocation(location)) {
// Do something
} else {
final status = await handler.Permission.location.status;
if (status.isPermanentlyDenied || status.isDenied) {
// ask the user to open the app setting
// from permission handler package you have
openAppSettings();
} else {
// show info dialog or something that the user need to enable location services
}
}
Please check this link. You must have to mention permission in POD file also.
clientViaUserConsent opens URL in browser but it said invalid request. this URL is generated internally from lib. I had double-checked my ClientId for both platforms but still face issues for getting AuthClient for create a calendar event.
I used the below packages to create events in the google calender.
googleapis: ^8.1.0
googleapis_auth: ^1.3.0
static final androidClientId = ClientId('xxxxxxxx.apps.googleusercontent.com');
static final iOSClientId = ClientId('xxxxxxx.apps.googleusercontent.com');
final _clientID = Platform.isAndroid ? EventProvider.androidClientId : EventProvider.iOSClientId;
final _scopes = [CalendarApi.calendarScope];
clientViaUserConsent(_clientID, _scopes, prompt).then((AuthClient client) {
var calendar = CalendarApi(client);
}
void prompt(String url) async {
print(" => $url");
if (await canLaunch(url)) {
await launch(URL);
} else {
throw 'Could not launch $url';
}
}
I am referring to this article for creating an event in google calendar.

You are seeing that error because the app hasn't been verified. If you are the app developer I advise you to check the App Verification FAQ to learn more about the verification steps. If you aren't the developer, you could try to enable the less secure app access but please be mindful of the consequences:
Less secure apps can make it easier for hackers to get in to your account, so blocking sign-ins from these apps helps keep your account safe.
I'm using the permission_handler package to request permissions on Android. A user is able to download a file to the downloads folder when he clicks on "Allow" in the Permission.storage popup. (We are calling it Permission.storage when the user installs the app.)
The issue is that if a user clicks on "Don't allow" the first time and "Allow" the second time in other flows in the app, we are still getting a permission denied error and the user is not able to download files like above flow. I've logged and checked the value of the status; it is coming as PermissionStatus.granted only which is expected. Any ideas on how to fix this?
Below is the error log
I/flutter ( 8170): could not download file FileSystemException: Cannot open file, path = '/storage/emulated/0/Download/codes.txt' (OS Error: Permission denied, errno = 13)
/// Permission snippet of first time
final permission =
GetPlatform.isAndroid ? Permission.storage : Permission.photos;
final status = await permission.status;
if (status != PermissionStatus.granted) {
await permission.request().isGranted;
}
/// Snippet when user clicks on download second time
final permission = Permission.storage;
final status = await permission.status;
debugPrint('>>>Status $status'); /// here it is coming as PermissionStatus.granted
if (status != PermissionStatus.granted) {
await permission.request().isGranted;
debugPrint('>>> ${await permission.status}');
}
directory = Directory('/storage/emulated/0/Download');
///perform other stuff to download file
when permission_handler package send request to user with request() function, we made in await so after close dialog you check second time if permission granted or not and if permission granted then perform other stuff to download file else you can again send request for the permission.
/// Snippet when user clicks on download second time
final permission = Permission.storage;
final status = await permission.status;
debugPrint('>>>Status $status'); /// here it is coming as PermissionStatus.granted
if (status != PermissionStatus.granted) {
await permission.request();
if(await permission.status.isGranted){
directory = Directory('/storage/emulated/0/Download');
///perform other stuff to download file
} else {
await permission.request();
}
debugPrint('>>> ${await permission.status}');
}
directory = Directory('/storage/emulated/0/Download');
///perform other stuff to download file
I'm sure this is a silly error on my behalf.
Using Permission_handler to request camera permissions on iOS.
On first attempt the dialog shows requesting permission and successfully approves or denies. However, if I deny the request first and try launching the camera again there is no dialog requesting permissions.
static Future<bool> checkCameraPermissions() async {
PermissionStatus status = await Permission.camera.status;
if (status.isUndetermined || status.isDenied) {
print('cam is denied or undetermined'); //Prints
PermissionStatus newStatus = await Permission.camera.request();
print(await Permission.camera.isDenied); //Prints 'true' immediately
if (newStatus.isDenied)
return false;
print('cam is approved!'); //Nope QQ
}
return true;
}
How do I force Permission_handler to request the user again?
According to Apple, the user response is stored and the dialog doesn't open again. You can read more about it over here
What you can do is show a dialog with steps to enable required permissions and open settings page.
Currently, I have a simple method that requests location permissions in my app using permission_handler. Everything works well the 1st time around when accepting/denying permissions. However, once the 1st dialog gets a response, calling .request() no longer opens the permissions request dialog.
Is there a way to trigger the dialog within the app after the user has already responded?
Here's my method:
Future<bool> requestLocationPermissions() async {
bool permissions = await Permission.locationWhenInUse.request().isGranted;
if (permissions) {
return true;
} else {
return false;
}
}
