Loading Local HTML with WebView Xamarin Forms

Question

I am trying to load a local HTML page in a webview with Xamarin forms. I am using the basic example in the dev docs although I can get a URL to load I can\'t get my own HTML

You must check the file properties for Build Action = BundleResource

Try this code to load local html file

var source = new HtmlWebViewSource();
        string url = DependencyService.Get().GetBaseUrl();
        string TempUrl = Path.Combine(url, "terms.html");
        source.BaseUrl = url;
        string html;
        try
        {
            using (var sr = new StreamReader(TempUrl))
            {
                html = sr.ReadToEnd();
                source.Html = html;
            }
        }
        catch(Exception ex){
            Console.WriteLine(ex.Message);
        }

Implementations of the interface for each platform must then be provided

iOS

[assembly: Dependency(typeof(BaseUrl))]
namespace yournamespace
{
   public class BaseUrl: IBaseUrl
   {
      public string GetBaseUrl()
      {
        return NSBundle.MainBundle.BundlePath;
      }
   }
}

Android

[assembly: Dependency (typeof(BaseUrl))]
 namespace yournamespace {
   public class BaseUrl_Android : IBaseUrl {
      public string Get() {
        return "file:///android_asset/";
     } 
   }
 }
