How do you customise the bottom navigation bar (tabbar) on a TabbedPage in Maui? (change font)

Question

How do you change the font family on the tab bar? In Xamarin forms I could extend the TabbedPageRenderer but not sure how to do it in Maui.
Any help is greatly appreciated.

Hello,

I could extend the TabbedPageRenderer but not sure how to do it in Maui.

You can use the following two ways to implement the feature.

Method 1: It is more recommened to use Handler rather than Renderer on MAUI.

You could use ITabbedViewHandler to customize your TabbedPage on each platform, please refer to the following documentations:

• Handlers.
• ITabbedViewHandler Interface.

Method 2: You could continue using TabbedPageRenderer on MAUI, please refer to Using Custom Renderers in .NET MAUI.

Update: For your case, after in-depth investigation, for your scenario, if you use Handler, you need to create a view of the corresponding platform to adapt. Please refer to Create a custom control using handlers to get more details.

As you could see, the steps will be cumbersome. Therefore, using Renderer to change font will be better choice for your scenario.
