Snack Bar in Xamarin Forms
Snack Bar in Xamarin Forms

Hello friends, notifying users about what happens in your mobile application is necessary. There is the Snack Bar which is good for this scenario. But in Xamarin.Forms by default, you don’t have the ability to call snack bar. Though by default you can’t do this, it is possible to make a Snack Bar in Xamarin Forms XAML exclusively. Without any platform specific code. This post is all about implementing this. Let’s dive in.

Here is the source code for the simple app built in this post.

Let’s Build the Snack Bar in Xamarin Forms

The implementation of this control is very simple. With a Templated view, we will create a simple control, design the snack bar’s UI with XAML and add appropriate Bindable properties.

The Snack Bar’s Look With XAML

When you look at a snack bar, it is pretty simple. A text field and a button. The button has only simple functions like close, cancel… So with the Templated View, adding these controls and the appropriate bindable properties to have the behavior of Android’s original snack bar will do it.

Now, for the snack bar in Xamarin.Forms to behave as a snack bar, and be a reusable control, we need to add properties which are bindable. These properties include the The message, text color, background color, font size, button text color and so on. Here are some properties I added, you could add more if you wish.

Opening and Closing the Snack Bar With Animations

A snack bar is supposed to appear at the bottom of the app’s user interface. It should appear with an animation moving it from the bottom to a position where it will be visible to the user. We will do this with a Bindable property called IsOpen. This property will cause an animation when changed, and cause the snack bar to show or hide its self. Here is the code to accomplish this.

To animate the opening and closing of our snack bar control, we use Xamarin Forms animations. Specifically, the Translate animation to move the control upward and downward when needed. And at a particular speed. Here is how we do it.

Using the Xamarin Forms Snack Bar

To use this control as a typical snack bar, it is important to note that its placement and the container in which it is used will affect its look and feel. In this example, we will place it in a Grid, at the bottom. That is, setting its VerticalOptions property to End. But if it was placed in a StackLayout for example, it would behave differently. So here is it.

With this, we have built a Snack Bar in Xamarin Forms. This control is not a native implementation and sure is an easier implementation. If need be, you could add additional properties. Or even more buttons, all that in XAML without any platform specific code.

    Good post!
    But may I know why did you use TemplatedView instead of ContentView for example? is there any pros. TemplatedView is nicer in WPF where it’s possible to really modify any UI element, but in X.F it’s just a container, like any View element?

    No big reason for doing that, Using a Templated view hinder’s the user from deleting the control’s content since it doesn’t have a content property whereas the ContentView has that property. instead, the templated view uses a template for its display, this template can just be changed.

    Is it possible to use a SnakBarService to snakeBar.Show() without put the control to the Page
