Learn to build augmented reality apps with flutter using the Apple ARKit plugin, and measure distances between two or more points in an AR scene.
Create a new Flutter project in Android Studio, enable iOS for the ARKit plugin, and set up the AR distance measurement screen as the first screen.
Implement the AR screen app bar by scaffolding the UI, adding a title text widget labeled 'Measure Distance', and setting the app bar background color to black.
Implement the ARKit scene view in Flutter by adding the ARKit plugin dependency, enabling the tap recognizer to select points, and handling the AR view creation callback.
Implement the callback function by creating an arcade controller instance to manage the arcade scene. Assign the arcade controller when the AR view is created.
Learn how to get the position of a tapped point in an AR view using hit test results and vector math to obtain x, y, z coordinates for distance measurements.
Add green spheres at each user tap to mark world positions in an ARKit scene, enabling multi-point distance measurement in the Flutter AR ruler app.
Draw lines between consecutive tap points in the AR ruler app, updating the last position and using unique line node names for each segment.
Calculate the distance between the newly tapped point and the last tap, draw the line between them, and display the distance text on the line in centimeters or meters.
Compute the midpoint between two 3d vectors and display the distance as floating text at that midpoint in a flutter ar ruler app; tap two points to draw the line.
Add a bottom-right floating action button to clear the AR scene by removing all nodes, including spheres, lines, and text, and then clear the node names list.
Implement the built-in dispose function to dispose the ARKit controller when the widget is removed, cleaning up the arcade controller instance in the AR distance measurement app.
Set up the iOS side by editing the port file, enable camera permission in Info.plist for AR, and run port and flutter commands to install and test the iOS app.
Connect your iOS device, configure the Xcode project, trust the developer, install the app, then test the AR ruler by tapping two points to display distances and clear the scene.
Welcome to this exciting course where you will learn how to build augmented reality (AR) applications for iOS using Flutter and Apple’s ARKit plugin. Augmented reality is rapidly growing in popularity, and AR-powered apps are now transforming how users interact with the world. In this course, we will dive into the world of AR development by guiding you step-by-step in building an AR distance measurement app. Whether you're a beginner or an experienced developer, this course will provide valuable insights into the world of augmented reality and how to integrate it with Flutter to create powerful cross-platform applications.
What is Augmented Reality (AR)?
Augmented reality is an interactive experience where computer-generated content is overlaid on the physical world. This combination of real and virtual elements allows users to engage with both the physical and digital world at the same time. AR is already revolutionizing industries such as gaming, education, architecture, and retail, and now it's easier than ever to create AR applications using Flutter.
In this course, you'll learn how to create an AR app that uses your device's camera to measure distances, lengths, and heights in real-time. The app will offer a convenient, on-the-go alternative to traditional measuring tools such as tape measures and rulers, leveraging the power of AR to offer precise measurements in a user-friendly interface.
What You Will Learn in This Course:
This course is designed to take you through the entire process of building an AR app using Flutter and Apple's ARKit plugin. You’ll learn how to:
Understand ARKit Basics: Before diving into development, we’ll introduce you to Apple’s ARKit, which is the framework that powers augmented reality experiences on iOS. You’ll understand how ARKit works and how it interacts with the device’s camera and sensors to track the real-world environment.
Set Up Flutter and ARKit Plugin: We’ll guide you through setting up your development environment by installing Flutter and integrating the ARKit plugin. This step is essential for creating AR experiences on iOS devices.
Build the AR Distance Measurement App: Once the foundational setup is complete, we’ll jump straight into coding. You’ll learn how to use Flutter and ARKit to build an AR distance measurement app that can measure physical distances, lengths, and heights. You’ll also get to explore how to visualize measurements in the real world through 3D representations.
Test and Debug Your App: Testing is an essential part of the development process. We will teach you how to test your AR app on real iOS devices, debug common issues, and optimize performance to ensure the app runs smoothly.
Why Flutter?
Flutter is an open-source UI software development kit (SDK) created by Google. It allows you to build beautiful, natively compiled applications for mobile, web, and desktop from a single codebase. This cross-platform capability is especially beneficial when developing AR applications because it allows you to deploy your app on both iOS and Android devices with minimal effort. In this course, you'll leverage Flutter's powerful features alongside ARKit to create seamless AR experiences for your users.
Who is This Course For?
This course is ideal for developers who want to learn how to create augmented reality applications using Flutter and ARKit. It is also suitable for those who want to dive into mobile development with AR technology but have little or no prior experience in AR or Flutter development. Basic knowledge of programming and mobile development concepts is helpful but not required.
By the end of this course, you'll have the knowledge and skills to develop your own AR applications with Flutter, creating innovative experiences that blend the digital and physical worlds.
