im facing an issue in one of my flutter apps. Im was using MapBox-SDK plugin but when I tested the app on IOS, it asked me to update my Mapbox-sdk to some version (which I did using pop install command). Now after everything, I am facing new errors in my info.plist file. I forgot to take a backup of my old info.plist file. Anyways, the new info.plist is:

<plist version="1.0">
<dict>
<string>YES</string>
<key>io.flutter.embedded_views_preview</key>
<true/>
<key>MGLMapboxAccessToken</key>

    <string>UIInterfaceOrientationLandscapeRight</string>
</array>
<key>UIViewControllerBasedStatusBarAppearance</key>
<false/>
</dict>
</plist

the error im facing while building up the app is:

The error error: unable to read property list from file: Info.plist is usually caused by missing config on the plist file. As previously mentioned in the comments, you need to have a value set on NSLocationWhenInUseUsageDescription. More details are explained in the package's docs.

<key>NSLocationWhenInUseUsageDescription</key>

I have been facing the same problem with a newly imported Flutter project. After some debugging, it seems like the issue was caused by a corrupt GoogleService-Info.plist file! Dunno why and how it was corrupted, because I have newly imported and existing project.

To solve this problem, you can follow those steps;

Open your project in XCode delete the existing GoogleService-Info.plist file download the original one from Firebase then reimport/re-copy this file into your project When this is done, run flutter clean then try running it in iOS Simulator

This worked for me, hope it solves your problem too.

In my case, it was because the Info.plist file was poorly formatted. It hasn't to do with XML format, because when I tried to find if that file was correctly formatted according to XML rules, it was ok, but when I tried to open the .plist file as a property list, I realized Xcode couldn't read it, so I added my keys using the property list utility, not the "code view".

I solved this issue by including <string/> after each <key>...</key> like this :

<key>NSPhotoLibraryUsageDescription</key>
<string /> 

<key>NSCameraUsageDescription</key>
<string /> 

<key>NSMicrophoneUsageDescription</key>
<string />
