Flutter-permission-handler: 2.1.1 swift compilation error

[jaumard]

My project doesn't compile anymore because of this:

/Users/jaumard/.pub-cache/hosted/pub.dartlang.org/permission_handler-2.1.1/ios/Classes/PermissionManager.swift:50:108: error: cannot convert value of type '[UIApplication.OpenExternalURLOptionsKey : Any]' (aka 'Dictionary<NSString, Any>') to expected argument type '[String : Any]'
