Xamarin.Forms.Breadcrumb

This is a breadcrumb navigation control that is completely automatic and uses the Navigation stack to get the page titles to generate the breadcrumbs.

The animation for the control is based on this article - A Cool Breadcrumbs Bar with Xamarin Forms Animations…

Basic example	Production Example

How to use it?

Install the NuGet package into all of your projects

Install-Package Xamarin.Forms.Breadcrumb

For iOS add the following to AppDelegate.cs > FinishedLaunching

BreadcrumbButtonRenderer.Init();

To add to a page the first thing we need to do is tell our XAML page where it can find the Breadcrumb control, which is done by adding the following attribute to our ContentPage:

<ContentPage x:Class="DemoApp.Pages.BasePage"
             xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             xmlns:breadcrumb="clr-namespace:Breadcrumb;assembly=Breadcrumb"
             xmlns:d="http://xamarin.com/schemas/2014/forms/design"
             xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
             mc:Ignorable="d">
    <ContentPage.Content>
        ...
    </ContentPage.Content>
</ContentPage>

Next up, just add the breadcrumb control onto that page and you're all set.

<breadcrumb:Breadcrumb Padding="15" VerticalOptions="Start" />
