Xamarin.Forms - Using StaticResource inside ResourceDictionary

Question

I have a little app in which i have a ContentPage with Syncfusion's SfChat, im trying to customize it a bit, so im using a ResourceDictionary like this:

<ContentPage.Resources>
        <syncTheme:SyncfusionThemeDictionary>
            <syncTheme:SyncfusionThemeDictionary.MergedDictionaries>
                <ResourceDictionary>
                    <x:String x:Key="SfChatTheme">CustomTheme</x:String>
                    <x:String x:Key="SfChatIncomingMessageAuthorFontFamily">MontserratRegular</x:String>
                </ResourceDictionary>
            </syncTheme:SyncfusionThemeDictionary.MergedDictionaries>
        </syncTheme:SyncfusionThemeDictionary>
    </ContentPage.Resources>

My problem is that the "SfChatIncomingMessageAuthorFontFamily" property needs a font from my app's resources as a static resource, so how do i use {StaticResource MontserratRegular} instead of just passing the font's name as an x:string ?

Answer 1

For exampl,use it on a label：

<ResourceDictionary>
    <OnPlatform
      x:Key="MediumFontFamily"
      x:TypeArguments="x:String"
      Android="sans-serif-medium"
      iOS="HelveticaNeue-Medium" />

</ResourceDictionary>

create styles :

<Style x:Key="MyLabel" TargetType="Label">
   <Setter Property="FontFamily"
        Value="{StaticResource MediumFontFamily}" />
</Style>

then use in label:

<Label Style="{StaticResource MyLabel}" Text="Hello World" />
