WebViewRenderer is deprecated from .NET MAUI; Doesn't suggest alternative

Question

I'm migrating Xamarin project to MAUI and migrated most of my code. However, Microsoft.Maui.Controls.Compatibility.Platform.Android.WebViewRenderer is giving a warning that it's deprecated with the following message: 'WebViewRenderer' is obsolete: This renderer is obsolete please try to use the corresponding handler/mapper.

I'm not sure what it means to "use the corresponding handler/mapper", and it doesn't provide alternate solution for it. Can anyone suggest what is the best way to replace Microsoft.Maui.Controls.Compatibility.Platform.Android.WebViewRenderer?

Hello,​

You can use WebViewHandler instead of WebViewRenderer.

With Handlers, the relationship between the framework and the platform is now inverted; the platform control only needs to handle the needs of the framework. Not only is this more efficient, but it is much easier to extend or override when needed. Gone are the days of needing to create Custom Renderers or Effects. The new architecture also makes the platform handlers much more suitable for reuse by other frameworks such as Fabulous, and experiments like Comet.

Here are a document about using handler.

If you can still use Custom Renderers in .NET MAUI.
