Flutter Widgets Cheat Sheet

In Flutter

Flutter is a popular open-source mobile application development framework that allows developers to create high-performance, visually appealing, and responsive mobile applications for both Android and iOS platforms. One of the key features of Flutter is its extensive collection of widgets, which are the building blocks of any Flutter application.

Widgets in Flutter are essentially UI components that can be used to create various elements of an application, such as buttons, text fields, images, and more. These widgets are highly customizable and can be easily modified to suit the specific needs of an application.

Flutter widgets are divided into two categories: stateless and stateful. Stateless widgets are those that do not change over time, while stateful widgets are those that can change based on user interactions or other events.

Some of the most commonly used Flutter widgets include:

  1. Text: This widget is used to display text on the screen. It can be customized with various fonts, colors, and styles.
  2. Image: This widget is used to display images on the screen. It supports various image formats and can be customized with different sizes and shapes.
  3. Button: This widget is used to create clickable buttons that perform specific actions when pressed.
  4. TextField: This widget is used to create text input fields that allow users to enter text.
  5. ListView: This widget is used to create scrollable lists of items.
  6. Container: This widget is used to create a rectangular container that can be customized with various colors, borders, and padding.

Flutter widgets are easy to use and can be combined to create complex UI elements. They are also highly performant, which means that Flutter applications can run smoothly even on low-end devices.

This cheat sheet provides an overview of the most commonly used Flutter widgets. For more detailed information, please refer to the official Flutter documentation. You’ll find a link below the cheat sheet. Enjoy!
