Mobile App Development – Grades 6-9
A 16-Week Self-Study Adventure
Course Description:
Have you ever used an app and thought, I have a cooler idea than this? Welcome to your chance to build it! This 16-week self-study course is your launchpad into the amazing universe of mobile app development. We’ve designed this journey specifically for creative minds like yours, starting from the very beginning and guiding you step-by-step. You don’t need any prior coding experience—just curiosity and a desire to create.
Through fun lessons, hands-on coding challenges, and a final project where you build your own app from scratch, you’ll gain real skills in designing and building applications. We’ll explore how to make apps that look great and work smoothly on different devices. Whether you dream of creating the next viral game, a helpful tool for your friends, or an app that solves a real-world problem, this course will give you the knowledge to turn your vision into reality. Get ready to stop just using apps and start creating them!
What You Will Achieve:
Uncover the Secrets of Apps: Learn the core concepts of mobile app development and understand the difference between building for iPhone (iOS) and Android.
Speak the Language of Code: Master the basics of Dart and the Flutter framework, powerful tools created by Google to build beautiful apps for any device from a single codebase.
Become a Digital Architect: Design app interfaces (the screens you see and touch!) that are easy to use and look amazing.
Build Real Features: Implement essential app functions like saving data, connecting to the internet, and navigating between screens.
Become a Bug Detective: Learn how to find and fix common problems in your code, an essential skill for any developer.
Launch Your Creation: Understand the process of preparing and deploying an application to app stores like the Google Play Store.
From Idea to App: Complete a final project where you build a fully functional mobile application from your own concept.
Your Developer Toolkit:
A Computer: Any Windows, macOS, or Linux computer that can connect to the internet is perfect. This will be your command center.
Internet Connection: You’ll need this to download software and access helpful online guides.
Smartphone or Tablet (Optional): Highly recommended for testing your apps on a real device to see how they look and feel!
Free Software: We will be using professional-grade tools that are completely free! This includes Android Studio (the main development environment) and VS Code (a popular code editor).

Weeks 1-2: Foundations of Mobile App Development
Lesson 1: Welcome to the App Universe
Your Mission:
Understand what mobile app development is all about.
Learn the three main ways apps are built: Native, Hybrid, and Cross-Platform.
Discover the key parts of the mobile world, like operating systems and app stores.
Key Vocabulary:
Native App: An app built in the native language of a specific device, like Swift for iPhones or Kotlin for Android phones. Think of it like a person who was born and raised in France—they speak perfect French. Native apps run fastest and smoothest.
Cross-Platform App: An app built with a single translator language (like Dart) that can then be understood by both iPhones and Androids. It’s like writing one book and having it expertly translated into multiple languages, saving a ton of time. This is what we will be doing!
IDE (Integrated Development Environment): Your all-in-one workshop. It’s a special program (like Android Studio) that gives you a code editor, testing tools, and everything you need in one place.
SDK (Software Development Kit): A specific toolbox for a platform. The Flutter SDK is like a giant box of special LEGO bricks made specifically for building apps.
Content:
Every day, you tap, swipe, and interact with dozens of mobile apps. But how do they go from an idea to something that lives on your phone?
There are three main paths developers can take:
1. The Native Path: This is the expert approach for a single platform. If you want to build an app only for iPhones, you’d use Apple’s tools and language (Swift). This gives the best performance and feels perfectly at home on the device. The drawback? If you then want to release it for Android, you have to build a completely separate app from scratch.
2. The Hybrid Path: This method uses web technologies (like HTML and JavaScript, which run websites) and wraps them in a simple app shell. It’s a way to get on both platforms quickly, but they often feel slower and can’t use all the phone’s cool features, like advanced camera functions.
3. The Cross-Platform Path: This is the best of both worlds approach we’ll be using! With a framework like Flutter, you write your code once, and it gets compiled into a fast, beautiful, native-feeling app for both iOS and Android. It’s efficient, powerful, and used by major companies like BMW and Google.
Your First Mission:
1. App Detective: Find one app you think is native to your phone (e.g., the Camera or Calculator app) and one you think might be cross-platform (e.g., a store app or a simple game). Why do you think so?
2. Set Up Your Workshop: Follow the official Flutter installation guide online to install Android Studio and the Flutter SDK on your computer. It might seem tricky, but it’s a huge first step!
Lesson 2: Meet Dart and Flutter
Your Mission:
Learn the fundamentals of the Dart programming language—the brains behind your app.
Understand Flutter Widgets, the building blocks of your app’s screen.
Create and run your very first Hello, World! app.
Key Vocabulary:
Dart: The programming language created by Google that we will use. It’s known for being clear, powerful, and easy to learn.
Flutter: The UI kit (your box of LEGOs!) that uses Dart to build the visual parts of your app.
Widget: Everything you see on a Flutter app screen is a Widget. A piece of text is a Widget. A button is a Widget. An icon is a Widget. You combine them to build your entire screen.
StatelessWidget: A what you see is what you get widget. It’s like a painted picture—it doesn’t change after it’s created. An app’s title or an icon are great examples.
StatefulWidget: A widget that can change its appearance while the app is running. Think of a like button—when you tap it, the number goes up. That change is its state.
* Hot Reload: Flutter’s superpower! You can make a change in your code and see it update on your screen almost instantly, without restarting the whole app.
Content:
Let’s start building! In Flutter, you arrange Widgets to create your user interface (UI). Think of it like building with LEGO bricks. You have basic bricks (Text, Icons), containers to hold them (Rows, Columns), and interactive bricks (Buttons).
Dart is the instruction manual that tells these bricks what to do. You’ll learn how to store information in variables (like a labeled box to hold a number or a word), make decisions with `if/else` statements, and create reusable instructions with functions.
For example, a variable in Dart looks like this:
`String greeting = ‘Hello, App Developer!’;`
This creates a box named `greeting` and stores the text ‘Hello, App Developer!’ inside it.
The biggest concept to grasp is the two types of widgets. A `StatelessWidget` is simple; it displays information that won’t change. A `StatefulWidget` is dynamic; it holds a state that can be updated, causing the screen to rebuild itself with new information. This is the magic behind interactive apps.
Time to Code!:
1. Create Your First Project: Open your IDE and create a new Flutter project.
2. Run the Starter App: The default project is a simple counter app. Run it on a simulator or your own device and see it in action!
3. Experiment with Hot Reload: Find the main text in the app and change it from You have pushed the button this many times: to something fun. Save your code and watch the screen update instantly. Welcome to the exciting world of mobile app development
