What is the difference between a stateful and stateless widget in Flutter?

Understanding the Difference Between Stateful and Stateless Widgets in Flutter

When it comes to developing mobile applications in Flutter, it's crucial to grasp the distinction between stateful and stateless widgets. Let's dive into the key differences:

Stateful Widgets:

• Definition: Stateful widgets in Flutter maintain and manage their own internal state, which can change over time.
• Characteristics: These widgets have mutable state properties that can be modified multiple times throughout the widget's lifecycle.
• Usage: Stateful widgets are ideal for components that require frequent updates or data changes.

Stateless Widgets:

• Definition: Unlike stateful widgets, stateless widgets do not have any internal state and remain unchanged once constructed.
• Characteristics: These widgets are immutable, meaning that their properties are set once and cannot be modified during runtime.
• Usage: Stateless widgets are suitable for displaying static content that does not need to be updated dynamically.

Understanding the difference between stateful and stateless widgets is essential for designing efficient and responsive Flutter applications. By leveraging the unique capabilities of each type of widget, developers can create user-friendly and performant mobile experiences.
