RiveRenderObject
. This allows you to override low-level methods such as advance
, beforeDraw
, and draw
to have more control and optionally perform additional operations. See below for example usage.
Note that this is a low-level API, and under most circumstances, it is preferable to make use of
RiveAnimation
or Rive
widgets instead.Example Code
The following is a basic example that demonstrates how to paint a Rive animation and advance a state machine using a custom RenderObject.StateMachineController
(or any other animation controller).
Example Usage
- Dynamically update component colors at runtime - Make use of a custom Rive render object to change a shape’s fill color, accessing it by name. This is helpful for when a color’s opacity is animating, but the color needs to be changed at runtime.
- Track a Rive component in Flutter - Track a Rive component’s position at runtime and overlay a Flutter widget or perform additional painting operations.
