Well-designed animations makes a UI feel more intuitive, contribute to the slick look and feel of a polished app, and improve the user experience. Flutter’s animation support makes it easy to implement a variety of animation types. Many widgets, especially Material Design widgets, come with the standard motion effects defined in their design spec, but it’s also possible to customize these effects.

The following resources are a good place to start learning the Flutter animation framework. Each of these documents shows, step by step, how to write animation code.

Animation types

Animations fall into one of two categories: tween- or physics-based. The following sections explain what these terms mean, and points you to resources where you can learn more. In some cases, the best documentation we currently have is example code in the Flutter gallery.

Tween animation

Short for in-betweening. In a tween animation, the beginning and ending points are defined, as well as a timeline, and a curve that defines the timing and speed of the transition. The framework calculates how to transition from the beginning point to the end point.

The documents listed above, such as the animations tutorial are not about tweening, specifically, but they use tweens in their examples.

Physics-based animation

In physics-based animation, motion is modeled to resemble real-world behavior. When you toss a ball, for example, where and when it lands depends on how fast it was tossed, how heavy it is, and how far off the ground. Similarly, dropping a ball attached to a spring falls (and bounces) differently than dropping a ball attached to a string.

Common animation patterns

Most UX or motion designers find that certain animation patterns are used repeatedly when designing a UI. This section lists some of the commonly used animation patterns, and tells you where you can learn more.

Animated list or grid

This pattern involves animating the addition or removal of elements from a list or grid.

  • AnimatedList example

    This demo, from the Sample App Catalog, shows how to animate adding an element to a list, or removing a selected element. The internal Dart list is synced as the user modifies the list using the plus (+) and minus (-) buttons.

Shared element transition

In this pattern, the user selects an element—often an image—from the page, and the UI animates the selected element to a new page with more detail. In Flutter, you can easily implement shared element transitions between routes (pages) using the Hero widget.

Staggered animation

Animations that are broken into smaller motions, where some of the motion is delayed. The smaller animations may be sequential, or may partially or completely overlap.
