How to integrate Badge into .NET MAUI ListView?

This article illustrates the process of integrating badges into a .NET MAUI ListView with a .NET MAUI BadgeView application.

Step 1: Initialize the ListView with Grouping Property

In the .NET MAUI application, initialize the ListView with grouping enabled. Grouping categorizes items within the ListView.

Step 2: Bind ListView to ViewModel Data Source

Bind the ItemsSource property of the ListView to a collection named Items within the ViewModel. This collection serves as the data source for the ListView.

Step 3: Initialize Badge View within DataTemplate

Inside the DataTemplate of the ListView, initialize the Badge View control and set its BadgeText property.

Step 4: Customize Badge Appearance

The BadgeView showcases a badge displaying the Count property of each item. Customize the badge appearance using the BadgeSettings property.

        <local:ViewModel/>
