Maui.Shell.MarkerModifier

Maui.Shell.MarkerModifier is a lightweight .NET MAUI library for customizing Shell visual markers (selection indicators).

Starting with version 10.2.0, the library uses Attached Properties. This allows you to style markers directly in XAML with full Hot Reload support.

✨ Features

  • 🎨 XAML Integration: Set Color, Height, and Width directly on the <Shell\> tag.
  • 🛠 Declarative UI: Manage visuals in XAML without extra C# code in MauiProgram.
  • 📱 Platform Support: Optimized for Windows (WinUI 3) with safe fallbacks for iOS/Android.

📦 Installation

Install the package via NuGet:

dotnet add package Maui.Shell.MarkerModifier --version 10.2.0

🚀 Getting Started

Setup in AppShell.xaml

Add the xmlns:marker namespace and apply properties to your root Shell element. This will update markers for all navigation items.

<Shell x:Class="MauiApp1.AppShell"
       xmlns="[http://schemas.microsoft.com/dotnet/2021/maui](http://schemas.microsoft.com/dotnet/2021/maui)"  
       xmlns:x="[http://schemas.microsoft.com/winfx/2009/xaml](http://schemas.microsoft.com/winfx/2009/xaml)"  
       xmlns:marker="clr-namespace:Maui.Shell.MarkerModifier.Extensions;assembly=Maui.Shell.MarkerModifier"  
       xmlns:local="clr-namespace:MauiApp1"  
       Title="MauiApp1"  
         
         
       marker:MarkerWindowsExtensions.Color="Red"  
       marker:MarkerWindowsExtensions.Width="30"  
       marker:MarkerWindowsExtensions.Height="30"\>

    <ShellContent Title="Home"  
                  ContentTemplate="{DataTemplate local:MainPage}"  
                  Route="MainPage" \>

    <ShellContent Title="Exit"  
                  ContentTemplate="{DataTemplate local:NewPage1}"  
                  Route="NewPage1" \>  
</Shell>

⚙️ Available Properties

Use the MarkerWindowsExtensions class to access these properties:

Property Description Type Default Value
Color The color of the selection indicator. Color Colors.Transparent
Height The thickness (height) of the marker line. double -1
Width The width of the marker line (Windows specific). double -1

⚠️ Important Changes
