In this tutorial series, we will see how to create a CardView in .Net MAUI using Border control. In .NET Maui provided Microsoft.Maui.Graphics library which provide us a consistent UI drawing API based on native graphics engines, thus making it easier for us to add borders, corners customisations, and shadows for most of the controls and layout contained in .NET MAUI. The new Border Control allows us to add Borders to a single element as a content (can be both a control and a Layout). This brings us a very flexible behavior to control of each corners: top-left, top-right, bottom-left, bottom-right, with our user interface, some of those cases can be adding the border to a button and rounding the upper left and lower right corners.

Introduction

Xamarin.Essentials

Xamarin.Essentials provides developers with cross-platform APIs for their mobile applications. Android, iOS, and UWP offer unique operating system and platform APIs that developers have access to all in C# leveraging Xamarin. Xamarin.Essentials provides a single cross-platform API that works with any Xamarin.Forms, Android, iOS, or UWP application that can be accessed from shared code no matter how the user interface is created.

Text-to-Speech

This enables an application to utilize the built-in text-to-speech engines to speak back text from the device and also to query available languages that the engine can support.

Coding Part

Steps

1. 1: Creating new Xamarin.Forms Projects
2. 2: Implementation of Text to Speech in Xamarin Forms

Step 1: Creating new Xamarin.Forms Projects

Create New Project by selecting "New Project" à "Xamarin Cross Platform App" and Clicking "OK". Note: Xamarin.Forms version should be greater than 5.0.

Then Select Android and iOS Platforms as shown below with Code Sharing Strategy as PCL or .Net Standard and Click OK.

Step 2: Implementation of Text to Speech in Xamarin Forms

In this step, we will see how to implement the functionality in Xamarin.Forms.

Platform Specific Changes:

• If your project's Target Android version is set to Android 11 (R API 30) you must update your Android Manifest with queries that are used with the new package visibility requirements.
• Open the AndroidManifest.xml file under the Properties folder and add the following inside of the manifest node:

Xamarin Forms App Changes:

• Add a reference to Xamarin.Essentials in your class:
• Text-to-Speech works by calling the SpeakAsync method with text and optional parameters, and returns after the utterance has finished.
• This API provide more options on how the audio is spoken back with SpeechOptions that allows setting the volume, pitch, and locale.

Create App Actions in Xamarin.Forms

App Actions can be created at any time, but are often created when an application starts. Call the SetAsync method to create the list of actions for your app.

If App Actions are not supported on the specific version of the operating system a FeatureNotSupportedException will be thrown. The following properties can be set on an AppAction:

1. Id: A unique identifier used to respond to the action tap.
2. Title: The visible title to display.
3. Subtitle: If supported a sub-title to display under the title.
4. Icon: Must match icons in the corresponding resources directory on each platform.

When your application starts register for the OnAppAction event. When an app action is selected the event will be sent with information as to which action was selected.
