- 1. Dart & Flutter Flutter Dart Introduction to Dart: programming language. Create mobile/web apps. Flutter: UI toolkit. Name: Nitesh Kumar Roll No.: 2108020100027 year: B.Tech (CSE) 3rd
- 2. Testing
- 3. Testing
- 6. Overview • Introduction to Dart and Flutter • Let’s Dart it. • Advantages of Dart • Basic of Dart • Introduction to Flutter • Features Today's Agenda Dart & Flutter
- 7. Flutter is an open-source UI framework by Google for building natively compiled applications for mobile, web, and desktop from a single codebase. Dart is the programming language used to develop Flutter applications, known for its speed and simplicity. Introduction to Dart and Flutter Dart & Flutter Building Cross- Platform Mobile Applications
- 8. Overview • Single Language • Hot Reload • Strongly Typed • Growing Ecosystem • Performance and User Experience: Let’s Dart it. Let’s Dart it. Dart Dart Dart is like the special language that's used to create apps with Flutter. It's the magic ink that developers use to bring their app ideas to life.
- 9. Advantages of Dart Single Language Strongly Typed Hot Reload Cross-platform Advantages of Dart Dart
- 10. • Performance (JIT and AOT compilation): Dart's efficient compilation techniques for fast execution. • Productivity (clean syntax and optional typing): A user-friendly approach for efficient coding. • Scalability (suitable for small to large projects): Dart works well for both small and large software projects. • Strong typing (compile-time error checking): Early detection of coding mistakes for more reliable software. • Null safety for reliable code: Ensuring your code is robust and dependable. • Asynchronous tasks: Handling time-consuming operations with ease. • Developer-friendly design: Dart is built with developers in mind, making it easy and enjoyable. Key Advantages
- 11. • Variables: ⚬ Declared with Types: int age = 30; ⚬ Dynamic Types: dynamic dynamicVar = "Hello"; • Data Structures: ⚬ Lists: List<int> numbers = [1, 2, 3]; ⚬ Maps: Map<String, int> studentGrades = {"Alice": 95, "Bob": 88}; • Control Flow: ⚬ Conditional Statements: if-else, else if, else ⚬ Loops: for, while, do-while ⚬ Switch Statement: switch Basics of Dart
- 12. • Functions: ⚬ Defined with return types: int add(int a, int b) => a + b; ⚬ Named Parameters: void greet({String name, String message}) {...} • Classes and Objects: ⚬ Object-Oriented: Dart supports the creation of classes and objects for structured programming. • Libraries and Packages: ⚬ Reusability: Dart leverages libraries and packages for code organization and sharing. • Null Safety: ⚬ Dart supports null safety, making code more reliable by preventing null pointer exceptions. Basics of Dart

- 15. bool isRaining = true; if (isRaining) { print("Remember to take an umbrella!"); } else { print("No need for an umbrella."); } Dart Programming
- 16. bool isRaining = true; String message = isRaining ? "Remember to take an umbrella!" : "No need for an umbrella."; print(message); Dart Programming
- 17. for (int i = 1; i <= 5; i++) { print("Number $i"); } Dart Programming int count = 0; while (count < 5) { print("Count is $count"); count++; }
- 18. String fruit = "apple"; switch (fruit) { case "apple": print("It's an apple."); break; default: print("It's something else."); } Dart Programming
- 19. Flutter is the first User Interface (UI) platform created specified for the world of ambient computing. Intro Flutter
- 20. Features Features Widgets Building blocks for app elements, like buttons and text. Boxes holding content with space for better presentation. Containers Navigation Moving between screens, guided paths for app flow. Designs Aesthetic, responsive, customizable.
- 21. Widgets A widget is a small, reusable piece of your app, like a building block, used to create different parts of your app's user interface. It can be a button, a bit of text, an image, or any interactive or display element. Widgets are essential elements you use to build your app's look and feel. Widgets Flutter
- 22. Designs Design in app development refers to the combination of aesthetics and functionality. It encompasses visual elements like colors, fonts, and layout, affecting how the app looks and user interaction. Material Design follows Google's guidelines, while Cupertino Design adheres to Apple's principles for consistent, pleasing, and platform-specific interfaces. Designs Flutter
- 23. Containers are like virtual boxes that structure an app's layout, arranging and aligning elements within them. They help organize content and contribute to a visually appealing and organized user interface following design principles like Material and Cupertino for platform-specific aesthetics. Containers in App Development Containers in App Developmenteeting Flutter
- 24. Navigation in app development guides users through different app screens or pages, enhancing the user experience. It ensures smooth transitions between sections, following design principles like Material and Cupertino for platform- specific navigation styles. Navigation Route Flutter
