[PermissionRequestInProgressException] Handling PermissionRequestInProgressException on iOS

[kuhnroyal]

🐛 Bug Report

On iOS, when the app goes to background while the permission dialog is showing (due to pressing power button or display timeout, usually for 30+ seconds or so) and the phone is activated again, the permission dialog is gone. Afterwards it is not possible to request a permission again because it will always throw PermissionRequestInProgressException.

Expected behavior

The plugin should detect this case and ensure that the permission can be requested again. Somehow the confirmationHandler needs to be cleaned up here: https://github.com/Baseflow/flutter-geolocator/blob/master/geolocator/ios/Classes/Handlers/PermissionHandler.m#L37

Reproduction steps

1. Make a call that requests the permission so that the dialog is showing (Geolocator.getCurrentPosition())
2. Press the power button and let it sleep for 30+ seconds so that the app goes fully to background
3. Wake the phone again, the dialog should be gone
4. Repeat 1.

Version: 6.1.4

• [x] :iphone: iOS

Hi @kuhnroyal

Thanks for filling this issue. I was able to reproduce it.

If you would like, I think Baseflow would love to see your PR!

I can't reproduce the issue on iOS14+, is this still an issue @kuhnroyal ?

[kuhnroyal]

I will try to test this again next week.

[kuhnroyal]

Sorry for the late reply, it seems the issue no longer occurs. Not sure what exactly fixed this, maybe the library is not allowing the app to go in background now.

[mvanbeusekom]

Re-opening this issue as @FelipeAndresLopez confirmed the issue is still occurring on recent versions of iOS.

[Frostlight]

Still happening as of now.

[frendcarlo]

I'm still having this issue in ios 16.2, any idea how to fix this? was there an option to cancel when get this exception PermissionRequestInProgressException ?

[Abisheik-IAN]

@frendcarlo yes we need to comment the native ios code inside plugin. open the file PermissionHandler.m and comment the return in lineno. 57 / (open the project in xcode and search the string "A request for location permissions is already running, please wait for it to complete before doing another request." and comment the return in lineno. 57)

[SShayashi]

Is there any updates? We have also the same issue.

[SShayashi]

I do not know why, but this event did not occur when launching the example app from Xcode instead of from Android Studio.

[SShayashi]

Currently, the policy is not to request again if the authorization request process is already running. https://github.com/Baseflow/flutter-geolocator/blob/c7dffa16311f5caf6ee3e48733be219183be9cf3/geolocator_apple/ios/Classes/Handlers/PermissionHandler.m#L46

However, considering the case where the location authentication on the iOS side does not return, the following option is better:

• Cancel the request already made and make a new request.
• Set a timeout.

[TimHoogstrate]

I've tested the following on iOS 16.6 en it seems to work as expected:

Run example app; request a permission like camera; click the power button to switch off the screen; click the power button to switch on the screen( wait 30 + seconds); Log into your iPhone; The Alert reopens. (multiple times)

If this issue still occurs please inform us about detailed steps to reproduce and probably OS version.

But there are multiple issues regarding the PermissionRequestInProgressException. I've reproduced it before only on a Simulator.

Kind regards,

[TimHoogstrate]

I've reproduced it with location permissions indeed. I'll label it as a bug. However, I'm not sure if it is a bug from the plugin. Related to: https://github.com/Baseflow/flutter-permission-handler/issues/783

Kind regards,

Commenting here to give #1217 some more exposure. This PR might fix the bug mentioned.

[ThienUKPC]

This still happens, has it been fixed yet?
