how do I know the riv file has finished playing?

[remantou]

I am using rive: 0.14.0-dev.8, and the RiveWidget works well.

My question is, how do I know the riv file has finished playing or if I want the riv file plays in a loop what should I do? With rive: 0.13 I can use stateMachineController.isActiveChanged.addListener(() {}) to do something.

The code is simply as follows and the controller's listener never get called.

@override 
void initState() {
    super.initState();
    var file = await File.path(somePath, riveFactory: Factory.rive);
    _controller = RiveWidgetController(file!);
    _controller!.addListener(() {
        /// never get called
        print('${_controller!.active}');
    });

    setState(() {
        _isInitialized = true;
    });
}

@override 
Widget build(BuildContext context) {
    if (!_isInitialized) {
        return CupertinoActivityIndicator();
    }

    return RiveWidget(controller: _controller!);
}

Thanks for your help!

You can set up custom events within the Rive Editor that you can listen to at runtime. This is a feature that is mostly now been replaced by data binding. Which is a better way to work with data in Rive, and will also allow you to broadcast events, as you can listen to these properties/triggers for changes in code.

You would set this up in the Editor to broadcast whatever information you need, at the time you need it.

The addListener you linked to above is only relevant for internal usage.

I'm closing this issue, but if you have difficulties with the above two approaches, Events or Data Binding, then please reach out to our community, where you can get assistance with understanding these concepts.
