Flutter has revolutionized mobile app development by allowing developers to create natively compiled applications from a single codebase. One of the key reasons behind Flutter's growing popularity is its extensive library of widgets that empower developers to build beautiful and interactive apps quickly and efficiently. In this blog, we’ll dive into essential Flutter widgets and explore how they contribute to building interactive user interfaces.
What Are Flutter Widgets?
In Flutter, everything is a widget. From a simple text field to complex interactive screens, widgets are the building blocks that define the visual structure and functionality of an app. There are two types of widgets in Flutter: Stateless and Stateful.
- Stateless widgets: These are static widgets that do not change during runtime. They display static content, such as text or images.
- Stateful widgets: These are dynamic widgets that can change over time in response to user interactions, such as buttons or forms.
Understanding these essential Flutter widgets is the first step toward becoming proficient in Flutter app development.
