I have tested it on my side.The badge effect works well,below is the step that might give you some insights.

As you mentioned, it could be achieved by creating a custom renderer for TabbedPage:

Step1: Move what is in BadgedTabbedPageRenderer.cs here into MyTabbedPageRenderer.cs

Step2: Add [assembly: ExportRenderer(typeof(TabbedPage), typeof(MyTabbedPageRenderer))] in AssemblyInfo.cs and MyTabbedPageRenderer.cs.

Step3: Add two lines in the page you want to achieve the badge effect in the child page.

plugin:TabBadge.BadgeColor="Red" 
plugin:TabBadge.BadgeText="1"
