How can I implement `onStateChange` in `StateMachineController.fromArtboard` when migrate from 0.13.x to 0.14.x?

[luu-elfie]

I'm going through the document for version 0.14.x but not find any migration code for onStateChange from StateMachineController.fromArtboard:

    final controller = StateMachineController.fromArtboard(
      artboard,
     "stateMachineName",
      onStateChange: (String stateMachineName, String stateName ) {
          // How can I listen to stateName change here?
      },
    );

Can anyone help me solve this?

Moreover, is there any equivalent solution to define a list of animation in 0.14.x like in 0.13.x:

      RiveAnimation.asset(
        AppAssets.RIVE_HELP_AND_SUPPORT_ROBOT,
        animations: ['headphoneOn', '0.Clear'], // I want to perform a set of animation here
        fit: BoxFit.contain,
      );

Thank you.

This functionality for onStateChange is not supported in the new runtime, with no plans to add it.

This is replaced with features such as:

• Databinding, and
• Events

Same for the ability to play multiple animations, we recommend configuring that with a single state machine instead. But you could also create a custom painter. See this example that paints a single animation, which you could extend to do multiple: https://github.com/rive-app/rive-flutter/blob/master/example/lib/examples/animation_painter.dart
