Introduction to Mobile Programming Unit1 [email protected] Importance of Mobile Programming Mobile applications have become a key part of our daily lives. From communication and entertainment to healthcare and finance, almost every industry relies on mobile apps to enhance user experiences. Businesses develop mobile apps to reach their customers more effectively, improve brand engagement, and increase revenue. The demand for mobile app developers is growing rapidly, making it an excellent career choice. In this course, we will explore mobile development using Flutter, a cross-platform framework that allows developers to build applications for both Android and iOS with a single codebase. 9.04.2025 [email protected] 2  What is Mobile Programming? Mobile programming refers to the process of designing, developing, and maintaining applications that run on mobile devices like smartphones and tablets. Unlike traditional software development, mobile programming involves dealing with different operating systems, screen sizes, and performance constraints. There are two main types of mobile apps: native apps, which are designed specifically for one platform (like iOS or Android), and cross-platform apps, which run on multiple operating systems. In this course, we focus on Flutter, which enables cross-platform development efficiently." 9.04.2025 [email protected] 3 Evolution of Mobile Development (brief history) Mobile application development has evolved significantly over the past two decades. Early mobile applications were simple, text-based, and limited in functionality. With the introduction of smartphones, mobile apps became more advanced, supporting rich graphics, connectivity, and complex features. Today, modern frameworks like Flutter and React Native enable developers to create high-performance applications with a single codebase for both Android and iOS. Understanding this evolution helps us appreciate how mobile technology has transformed the world and where it is heading next 9.04.2025 [email protected] 4  Mobile Platforms & Development Approaches There are two main approaches to mobile development: native and cross-platform. Native development means building apps specifically for one platform, using Swift for iOS or Kotlin/Java for Android. While native apps offer high performance and deep integration with system features, they require separate development efforts for each platform. On the other hand, cross-platform development frameworks like Flutter and React Native allow developers to write a single codebase that works on both iOS and Android, significantly reducing development time and cost. In this course, we focus on Flutter due to its flexibility and growing industry adoption 9.04.2025 [email protected] 5  Why Choose Flutter for Mobile Development? Flutter is an open-source UI framework developed by Google that allows developers to create high-performance mobile applications for multiple platforms using a single codebase. Unlike other cross-platform frameworks, Flutter offers near-native performance and a rich set of pre-built widgets, making it an ideal choice for modern mobile applications. Companies like Google, Alibaba, and BMW are using Flutter to build high-quality applications. Learning Flutter provides students with a valuable skill that is in demand in the job market 9.04.2025 [email protected] 6 How Flutter Works? Flutter uses the Dart programming language and a unique rendering engine to create visually appealing and smooth applications. The framework consists of widgets that define the UI, allowing developers to customize designs easily. Flutter’s ‘hot reload’ feature enables real-time changes during development, speeding up the coding process. Additionally, Flutter supports third-party integrations, making it a powerful tool for building scalable mobile apps. By understanding its architecture, students can efficiently create feature-rich applications with minimal effort. 9.04.2025 [email protected] 7 Tools & Setup for Flutter Development Before developing with Flutter, we need to set up our environment. The key requirements are installing Flutter SDK, Android Studio or Visual Studio Code, and configuring necessary emulators for testing. Flutter provides built-in debugging and performance tools to assist developers. By following a structured setup process, we ensure a smooth development experience. In this session, we will guide students through installing the required tools and running their first Flutter application. 9.04.2025 [email protected] 8 Career Opportunities in Mobile Development The mobile development industry offers a wide range of career opportunities. Developers can work in various roles, such as mobile app developers, UI/UX designers, or full-stack mobile engineers. With companies increasingly shifting towards mobile-first strategies, skilled mobile developers are in high demand. Flutter, being a widely adopted cross-platform framework, provides an excellent opportunity for developers to secure high-paying jobs in both startups and multinational companies. Learning Flutter enhances career prospects, whether students aim to work for a company or build their own applications 9.04.2025 [email protected] 9 Flutter Unit 2
