Uno Material Design Guideline is a resource for designers and software developers that combines Material and Uno design guidance in single document. It is an easy way to kickstart design and implementation of cross-platform experiences with unified Material design system look and feel, using Sketch and Uno Platform.

Download the Uno Platform Design Guidelines sketch file to get started.

It includes:

• Uno-Material components
• Uno type resource names
• Uno asset naming and export guidance

Getting Started

1. Install the nuget package Uno.Material.
2. Unless you want our default color palette (inspired by our Uno logo), you'll want to override the following color resources in you application. We suggest creating a ColorPaletteOverride.xaml ResourceDictionary. For more information on the color system, consult this page for all the official documentation and tools to help you create your own palette. Here is what ColorPaletteOverride.xaml would contain if you want both light and dark theme.

<ResourceDictionary
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">

	
	<ResourceDictionary.ThemeDictionaries>
		
		<ResourceDictionary x:Key="Light">
			<Color x:Key="MaterialPrimaryColor">#5B4CF5</Color>
			<Color x:Key="MaterialPrimaryVariantDarkColor">#353FE5</Color>
			<Color x:Key="MaterialPrimaryVariantLightColor">#B6A8FB</Color>
			<Color x:Key="MaterialSecondaryColor">#67E5AD</Color>
			<Color x:Key="MaterialSecondaryVariantDarkColor">#2BB27E</Color>
			<Color x:Key="MaterialSecondaryVariantLightColor">#9CFFDF</Color>
			<Color x:Key="MaterialBackgroundColor">#FFFFFF</Color>
			<Color x:Key="MaterialSurfaceColor">#FFFFFF</Color>
			<Color x:Key="MaterialErrorColor">#F85977</Color>
			<Color x:Key="MaterialOnPrimaryColor">#FFFFFF</Color>
			<Color x:Key="MaterialOnSecondaryColor">#000000</Color>
			<Color x:Key="MaterialOnBackgroundColor">#000000</Color>
			<Color x:Key="MaterialOnSurfaceColor">#000000</Color>
			<Color x:Key="MaterialOnErrorColor">#000000</Color>
			<Color x:Key="MaterialOverlayColor">#51000000</Color>
		</ResourceDictionary>

		
		<ResourceDictionary x:Key="Dark">
			<Color x:Key="MaterialPrimaryColor">#B6A8FB</Color>
			<Color x:Key="MaterialPrimaryVariantDarkColor">#353FE5</Color>
			<Color x:Key="MaterialPrimaryVariantLightColor">#D4CBFC</Color>
			<Color x:Key="MaterialSecondaryColor">#67E5AD</Color>
			<Color x:Key="MaterialSecondaryVariantDarkColor">#2BB27E</Color>
			<Color x:Key="MaterialSecondaryVariantLightColor">#9CFFDF</Color>
			<Color x:Key="MaterialBackgroundColor">#121212</Color>
			<Color x:Key="MaterialSurfaceColor">#121212</Color>

			<Color x:Key="MaterialOverlayColor">#51FFFFFF</Color>
		</ResourceDictionary>
	</ResourceDictionary.ThemeDictionaries>
</ResourceDictionary>

3. Initialize the material resources. The order in which the different resources are loaded is important. Add this to App.xaml

<MaterialColors xmlns="using:Uno.Material"
				OverrideSource="ms-appx:///ColorPaletteOverride.xaml" />
<MaterialResources xmlns="using:Uno.Material" />

4. (Optional) The material ProgressBar is built on top for the WinUI ProgressBar so make sure you include the appropriate resources in your App.xaml

	<Application.Resources>
		<ResourceDictionary>
			<ResourceDictionary.MergedDictionaries>
				
				<XamlControlsResources xmlns="using:Microsoft.UI.Xaml.Controls"/>

				<MaterialColors xmlns="using:Uno.Material"
								OverrideSource="ms-appx:///ColorPaletteOverride.xaml" />
				<MaterialResources xmlns="using:Uno.Material" />
				
				
			</ResourceDictionary.MergedDictionaries>
		</ResourceDictionary>
	</Application.Resources>

5. Start using the styles in your pages!

• To use styles, just find the name of the style from our documentation or sample app and use it like this

<Button Content="CONTAINED"
	Style="{StaticResource MaterialContainedButtonStyle}"/>

6. In order to display the appropriate font with the material styles on Webassembly, make sure that the Roboto font is defined on font.css located at [YourProject].Wasm/WasmCSS. This make sure that the font is loaded correctly Related Issue. It should look like this:

@font-face {
  font-family: "Symbols";
  /* winjs-symbols.woff2: https://github.com/Microsoft/fonts/tree/master/Symbols */
  src: url(data:application/x-font-woff;charset=utf-8;base64,[...]);
}

@font-face {
  font-family: "Roboto";
  src: url(data:application/x-font-woff;charset=utf-8;base64,[...]);
}

body::after {
	font-family: 'Roboto';
	background: transparent;
	content: "";
	opacity: 0;
	pointer-events: none;
	position: absolute;
}

7. (Optional) Set material styles as the default for your whole application.

    <MaterialResources xmlns="using:Uno.Material" WithImplicitStyles="True" />
   

   Alternatively, if you wish to only have the default styles for certain controls, simply add the implicit styles to your App.xaml:

    <Application.Resources>
    	<ResourceDictionary>
    		<ResourceDictionary.MergedDictionaries>
    			<MaterialColors xmlns="using:Uno.Material" />
    			<MaterialResources xmlns="using:Uno.Material" />
   
   
    			<ResourceDictionary>
    				<Style TargetType="Button" BasedOn="{StaticResource MaterialContainedButtonStyle}"/>
    				<Style TargetType="TextBox" BasedOn="{StaticResource MaterialFilledTextBoxStyle}"/>
    			</ResourceDictionary>
    		</ResourceDictionary.MergedDictionaries>
    	</ResourceDictionary>
    </Application.Resources>
   

   Learn more about implicit styles from the Microsoft documentation here

8. (Optional) Per-control customization. Just like WinUI, we documented a set of control-specific resources you can override to further customize our controls. For example, if you would like change the CornerRadius of all the Buttons using our material styles, you could simply override the ButtonBorderRadius value in your resources (in App.xaml would be the simplest way to put the following code)

<CornerRadius x:Key="ButtonBorderRadius">4</CornerRadius>

9. (Optional) If you are using our ToggleSwitches to get proper Material styling in Android there is some extra code to be added to the Android Project Head. (Click the component name to see how to set them up)

10. (Optional) If you are using our DatePickers, and TimePickers to get proper Material styling in Android there is some extra code to be added to the Android Project Head. (Click the component name to see how to set them up)

Styles for basic controls

Controls Setup (Specialized)

ToggleSwitch

If you are using our ToggleSwitches to get the proper native colors on android their is some modification needed. The reasoning for this is to apply the native android shadowing on the off value of the ToggleSwitch, and proper focus shadow colors when ToggleSwitches are clicked

1. From your Android project head go to YourProject.Droid/Resources/values/Styles.xml Inside your AppTheme add two item's "colorControlActivated" (the on color for your ToggleSwitches thumb) and "colorSwitchThumbNormal" (the off color for your ToggleSwitches thumb) you may add your colors here directly, for example #ffffff, or by files (see our example code below)

<?xml version="1.0" encoding="utf-8" ?>
<resources>
	<style name="AppTheme" parent="Theme.AppCompat.Light">

		
		<item name="colorControlActivated">@color/MaterialPrimaryColor</item>
		<item name="colorSwitchThumbNormal">@color/MaterialSurfaceVariantColor</item>
	</style>
</resources>

2. (Optional) If your application uses Light/Dark color palettes. 2.1 Inside the Styles.xml file change the AppTheme's parent to Theme.Compat.DayNight

<?xml version="1.0" encoding="utf-8" ?>
<resources>
	<style name="AppTheme" parent="Theme.AppCompat.DayNight">

		
		<item name="colorControlActivated">@color/MaterialPrimaryColor</item>
		<item name="colorSwitchThumbNormal">@color/MaterialSurfaceVariantColor</item>
	</style>
</resources>

2.2 From your Android project head go to YourProject.Droid/Resources/values create a file called "colors.xml", inside include your "Light" theme colors.

<?xml version="1.0" encoding="utf-8" ?>
<resources>
	<color name="MaterialPrimaryColor">#5B4CF5</color>
	
	<color name="MaterialSurfaceVariantColor">#FFFFFF</color>
</resources>

2.3 From your Android project head go to YourProject.Droid/Resources create a folder called "values-night", inside the folder add a file called "colors.xml", and inside the file include your "Dark" theme colors.

<?xml version="1.0" encoding="utf-8" ?>
<resources>
	<color name="MaterialPrimaryColor">#B6A8FB</color>
	
	 <color name="MaterialSurfaceVariantColor">#808080</color>
</resources>

2.3 (Optional) If you have changed the material color palette for your application (2.) then there are two more colors that must be overridden for android native ToggleSwitch disabled colors to be properly applied. Colors are named PrimaryVariantDisabledThumbColor and SurfaceVariantLightColor, they can be overridden in your colors.xaml file. PrimaryVariantDisabledThumbColor is a non-transparent version of PrimaryDisabled color ("Light") in "Light" palette, and a non-transparent version of PrimaryMedium color ("Dark") in "Dark" palette. SurfaceVariantLightColor is the Surface color however in "Light" Palette is an off white color to be visible on light backgrounds.

	<ResourceDictionary.ThemeDictionaries>

		
		<ResourceDictionary x:Key="Light">
			
			<Color x:Key="PrimaryVariantDisabledThumbColor">#E9E5FA</Color>
			
			<Color x:Key="SurfaceVariantLightColor">#F7F7F7</Color>
		</ResourceDictionary>

		
		<ResourceDictionary x:Key="Dark">
			
			<Color x:Key="PrimaryVariantDisabledThumbColor">#57507C</Color>
			<Color x:Key="SurfaceVariantLightColor">#121212</Color>
		</ResourceDictionary>
	</ResourceDictionary.ThemeDictionaries>

DatePickers and TimePickers

If your application uses DatePickers and/or TimePickers (these are native components). To apply your material colors to these android components, do the following (this will affect every DatePicker/TimePicker in the application).

1. From your Android project head go to YourProject.Droid/Resources/values/Styles.xml Inside your AppTheme add two item's "datePickerDialogTheme" (the style for your DatePicker) and "timePickerDialogTheme" (the style for your TimePicker), and a new Style with the MaterialPrimary Color as AccentColor (see our example code below)

<?xml version="1.0" encoding="utf-8" ?>
<resources>
	<style name="AppTheme" parent="Theme.AppCompat.Light">

		
		<item name="android:datePickerDialogTheme">@style/AppCompatDialogStyle</item>
		<item name="android:timePickerDialogTheme">@style/AppCompatDialogStyle</item>
	</style>

	<style name="AppCompatDialogStyle" parent="Theme.AppCompat.Light.Dialog">
		<item name="colorAccent">@color/MaterialPrimaryColor</item>
	</style>
</resources>

2. (Optional) If your application uses Light/Dark color palettes. 2.1 Inside the Styles.xml file change the AppTheme's parent of both styles to Theme.Compat.DayNight

<?xml version="1.0" encoding="utf-8" ?>
<resources>
	<style name="AppTheme" parent="Theme.AppCompat.DayNight">

		
		<item name="android:datePickerDialogTheme">@style/AppCompatDialogStyle</item>
		<item name="android:timePickerDialogTheme">@style/AppCompatDialogStyle</item>
	</style>

	<style name="AppCompatDialogStyle" parent="Theme.AppCompat.DayNight.Dialog">
		<item name="colorAccent">@color/MaterialPrimaryColor</item>
	</style>
</resources>

2.2 From your Android project head go to YourProject.Droid/Resources/values create a file called "colors.xml", inside include your "Light" theme colors.

<?xml version="1.0" encoding="utf-8" ?>
<resources>
	<color name="MaterialPrimaryColor">#5B4CF5</color>
</resources>

2.3 From your Android project head go to YourProject.Droid/Resources create a folder called "values-night", inside the folder add a file called "colors.xml", and inside the file include your "Dark" theme colors.

<?xml version="1.0" encoding="utf-8" ?>
<resources>
	<color name="MaterialPrimaryColor">#B6A8FB</color>
</resources>

Migration

1.0 to 1.1

• Color Palette Override

  Now you have the possibility to override the Material color palette with your own color palette. See the #Getting Started section for more details.

    <MaterialColors xmlns="using:Uno.Material"
    				OverrideSource="ms-appx:///ColorPaletteOverride.xaml" />
  

• Namespace breaking changes

  BREAKING CHANGE: Everything (controls, extensions, converters, ...), previously under Uno.Material.* or Uno.Cupertino.*, has now been moved under Uno.Material or Uno.Cupertino.

    xmlns:um="using:Uno.Material"
    xmlns:uc="using:Uno.Cupertino"
  

• Some controls have been moved to Uno.Toolkit.UI

  List of the controls and styles that have been moved to Uno.Toolkit.UI:

  Controls	StyleNames
  Card	MaterialOutlinedCardStyle <br> MaterialElevatedCardStyle <br> MaterialAvatarOutlinedCardStyle <br> MaterialAvatarElevatedCardStyle <br> MaterialSmallMediaOutlinedCardStyle <br> MaterialSmallMediaElevatedCardStyle
  Chip	MaterialFilledInputChipStyle<br>MaterialFilledChoiceChipStyle<br>MaterialFilledFilterChipStyle<br>MaterialFilledActionChipStyle<br>MaterialOutlinedInputChipStyle<br>MaterialOutlinedChoiceChipStyle<br>MaterialOutlinedFilterChipStyle<br>MaterialOutlinedActionChipStyle
  ChipGroup	MaterialFilledInputChipGroupStyle<br>MaterialFilledChoiceChipGroupStyle<br>MaterialFilledFilterChipGroupStyle<br>MaterialFilledActionChipGroupStyle<br>MaterialOutlinedInputChipGroupStyle<br>MaterialOutlinedChoiceChipGroupStyle<br>MaterialOutlinedFilterChipGroupStyle<br>MaterialOutlinedActionChipGroupStyle
  Divider	MaterialDividerStyle

• Some controls have been removed

  List of the controls and styles that have been removed from Uno.Themes:

  Controls	StyleNames
  BottomNavigationBar	MaterialBottomNavigationBarStyle
  ExpandingBottomSheet	MaterialExpandingBottomSheetStyle
  ModalStandardBottomSheet	MaterialModalStandardBottomSheetStyle
  StandardBottomSheet	MaterialStandardBottomSheetStyle
  SnackBar	MaterialSnackBarStyle

  • BottomNavigationBar was replaced by TabBar in Uno.Toolkit.UI, but it is not an exact 1:1 replacement. In the mean time, if you really need the badge and/or other customizability, two options are available:

    Import locally the old sources (control + style) from Uno.Themes;

    OR

    Copy the MaterialBottomTabBarItemStyle from Uno.Toolkit.UI, and modify the style to suit your needs. (Note that there are two copies of the style, one for iOS and Android and one for rest of the platforms: UWP, Skia, WASM, etc...);

  • For StandardBottomSheet and ModalStandardBottomSheet It's replaced by using a Flyout and the MaterialFlyoutPresenterStyle that is allowing you to have a bottom sheet.

    For example:

      <Flyout Placement="Full"
            LightDismissOverlayMode="On"
            FlyoutPresenterStyle="{StaticResource MaterialFlyoutPresenterStyle}">
      	<Grid MaxHeight="370"
      		  VerticalAlignment="Bottom">
      		...Your bottom sheet content...
      	</Grid>
      </Flyout>
    

  • For SnackBar: so far no replacement for SnackBar has been added to Uno.Toolkit.UI, but it's planned to add one in a future version.
