Material3.Avalonia

A modern Material Design 3 theme library for Avalonia applications.

Status: Work in progress / early preview.
Controls coverage is still limited; the M3 theming foundation is mostly in place.

Requirements

• Avalonia: 12.1.2+
• Target Framework: .NET 8.0 or .NET 10.0

Progress on implemented controls is tracked in issue #1.

Getting started

1) Add the library to your app

2) Wire up styles and the theme (App.axaml)

Add the XML namespace for the theme type (adjust if you changed the CLR namespace):

<Application xmlns="https://github.com/avaloniaui"
             xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
             xmlns:theme="clr-namespace:Material3.Avalonia.Theme;assembly=Material3.Avalonia">
    <Application.Styles>
        <theme:MaterialTheme Mode="Light"
                             Variant="TonalSpot"
                             SourceColor="#6750A4"
                             Contrast="Standard"
                             MotionScheme="Standard"
                             SymbolStyle="Rounded"
                             SymbolWeight="400"
                             SymbolGrade="0"
                             SymbolIsFilled="False" />
    </Application.Styles>
</Application>
