Widget catalog

A catalog of some of Flutter's rich set of widgets.

Create beautiful apps faster with Flutter's collection of visual, structural, platform, and interactive widgets. In addition to browsing widgets by category, you can also see all the widgets in the widget index.

Design systems #

Flutter ships with two design systems as part of the SDK.

Cupertino Beautiful and high-fidelity widgets that align with Apple's Human Interface Guidelines for iOS and macOS. Material design Visual, behioral, and motion-rich widgets implementing the Material 3 design specification.
