Getting iOS localizable string keys in mic permission request dialog box when trying place a call in iOS ?

[RageshAntonyHM]

Issue Summary

When I try to place a call without microphone permission enabled, I am getting a dialog box like this

It shows "localisation string keys" instead of it's value. Why? These keys come from twilio_voice plugin's iOS folder's Localizable.strings file.

Steps to Reproduce

This is the code:

        ref.read(twilioVoiceProvider).call.place(
              from: from,
              to: '+1$phoneNumber',
              extraOptions: extra,
            );
        ref.read(navNotifierProvider.notifier).onAnswerCall();
        ref.read(twilioNotifierProvider.notifier).setCallToName(prettyNumber);
        ref.read(callTimerProvider.notifier).startCallTimer();

please help me.

Have you already allowed mic on permission when first install?
And also added in the info plist file the request for audio and such? included the xcode allow audio as well.

No. I didn't allowed mic on permission when first install. This is intentional flow due to a bug ticket that is "IF mic permission not allowed by any means and a call is initiated, this kind of dialog appears".

And, info.plsit already added.

	<key>NSMicrophoneUsageDescription</key>
	<string>Microphone is used for in-app calls</string>

<key>UIBackgroundModes</key>
	<array>
		<string>audio</string>

How about a flow that when trying to call, Request the mic audio again before start calling.
IOS is quite strict on permission so it might trouble on the callkit side maybe.

Sorry. I didn't get you. I am actually an Android dev who working in a Flutter project. Can you please explain in detail ?

Flow for start calling without accepting mic permission,

my question are you using permission_handler?

flow:

- Not accepting mic permission
- UI on start calling
- Before calling   ref.read(twilioVoiceProvider).call.place(
              from: from,
              to: '+1$phoneNumber',
              extraOptions: extra,
            );
- Try to create a blocker first if you are using permission_handler
  e.g.

   if(!(await.Permission.microphone.isGranted)}{
    // Call request for mic/audio
   await Permission.microphone.request();
   }else{
        ref.read(twilioVoiceProvider).call.place(
              from: from,
              to: '+1$phoneNumber',
              extraOptions: extra,
            );
        ref.read(navNotifierProvider.notifier).onAnswerCall();
        ref.read(twilioNotifierProvider.notifier).setCallToName(prettyNumber);
        ref.read(callTimerProvider.notifier).startCallTimer();
   }

Thus this helps?

The error arises in this block

in the file ios/Classes/SwiftTwilioVoicePlugin.swift, in the func makecall(..)

            self.checkRecordPermission { (permissionGranted) in
                if (!permissionGranted) {
                    let alertController: UIAlertController = UIAlertController(title: String(format:  NSLocalizedString("mic_permission_title", comment: "") , SwiftTwilioVoicePlugin.appName),

                        return
                    }
                    currentViewController.present(alertController, animated: true, completion: nil)

                }
            }

The keys are returned instead of values

I fixed the issue. Can I create a PR and is the project is alive (no release for 14 months) so it will be merged and published to pub.dev?
