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
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.
• Value Widgets
• Example: Text widget
• Style Widgets
• Example: Center widget
• Composition Widgets
• Example: Container widget
• Navigation Widgets
• Example: AppBar widget

Bringing the chapter together: Composing them in a custom widget

Stateful vs. Stateless widgets

• 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).
