3. Everything is widgets
- Chapter Synopsis: Widgets are super-important to Flutter since they're the building blocks of every Flutter app. We show why and provide the motivation and basic tools to create widgets. Reminder about widgets
- Composition
- Define composition
- Provide real-world examples
- Why it is such a win
- Comparison with Web Components, React, Angular, and Vue
- The categories of Flutter UI widgets
- Value Widgets
- Example: Text widget
- Style Widgets
- Example: Center widget
- Composition Widgets
- Example: Container widget
- Navigation Widgets
- Example: AppBar widget
- For each category, we'll explain why we'd use them, what they have in common, and give one or two examples of the most fundamental and needed widgets in each category.
- What is state?
- How to create a custom stateless widget (Note: creating a stateful widget is complex so we're saving it for the State chapter).
