Xamarin Forms - passing value from Xaml.cs to custom renderer

I have a page called MapPage.Xaml.cs and on that page's constructor I have an argument called bool isFireHazard. In my Custom Renderer CustomMapRenderer.cs in my Android project, I want to check that boolean to see whether it is true.

How do I reference this boolean from my custom renderer?

You need to store isFireHazard passed to constructor in CustomMap object member. Then in CustomMapRenderer you can access it as 

protected override void OnElementChanged (ElementChangedEventArgs<xxx> e)
    {
       base.OnElementChanged(e);

       if (e.NewElement != null)
       {
          var formsMap = (CusomMap)e.NewElement;
          if(formsMap.isFireHazard)
          {
          }
       }
    }
