I have the same problem

[evelyne24]

Same, it crashes the first time it requests permissions, after which it returns null.

Same issue, I tried it using real machine(iPhone7, iOS12.2) and emulator(iOS12.2, iOS11.4, iOS10.3), however both crashed.

@xiaobeiy, @evelyne24, @BPHvZ and @HishikiKenta, have you added the necessary permissions in your Info.plist file? If those permissions are missing the application will indeed crash when trying to request permissions. Please see the Info.plist in our example app for details.

[HishikiKenta]

I didn't add it. It works! Thank you @mvanbeusekom .

[alnaughty]

where can I find Info.plist? on to put the permissions on ios

[mvanbeusekom]

@alnaughty it is located in the ios/Runner folder inside the root of you Application.
