â?&#x2018;ListView â?? Listview is a view presenting list of data, especially long list that require scrolling.

❑WebView ❏ WebView is a view for displaying web and HTML content in your app. Unlike OpenUri, which takes the user to the web browser on the device, WebView displays the HTML content inside your app.

Example <WebView x:Name="webView" WidthRequest="1000" HeightRequest="1000" Source=“ https://docs.microsoft.com/en-us/xamarin/xamarin-forms/user-interface /webview?tabs=windows ” />

â?&#x2018;Maps â?? Xamarin.Forms.Maps uses the native map APIs on each platform. This provides a fast, familiar maps experience for users, but means that some configuration steps are needed to adhere to each platforms API requirements. Once configured, the Map control works just like any other Xamarin.Forms element in common code.
