Hide and make widget invisible when using captureMotionWithStream()

[qiwen98]

Hi, thanks for the great work!

Is it possible to hide the Render widget (e.g. the AnimatedExampleWidget in main.dart) when using the captureMotionWithStream, I wish to render and record the widget in the background by not showing the rendering process. CaptureMotionFromWidgetWithStream sounds like the feature I want, but I have no idea how to modify it in main.dart. I would appreciate any help.

Sure. CaptureMotionFromWidgetWithStream has a widget parameter input. This function will provide your widget a off-screen context, from which it is being build.

Thefore you can simply do:

final stream = controller.captureMotionFromWidgetWithStream(AnimatedExampleWidget(), ...);

This code is not written in your widget tree, but you can put it in your initState() for example.

Does this answer your question?

I had an animated screen which I wanted to download when the user presses the download button. I tried doing it by captureMotionFromWidgetWithStream(MyAnimatedClass,.....). But this was calling the initState of MyAnimationClass multiple times and wasn't able to render the animation. The video was being saved but it was just a blank screen video.

If you display the animation don't use ...fromWidget. Nonetheless I believe that is an issue in your code. Please try your problem with a default widget and compare if the issue still arises. I am unable to determine what's going wrong just from your text, but you might be required to preload the data in your initstate and then pass it to your to-be-rendered widget.

I have to use the animations and render them in background. Using captureMotionFromWidgetWithStream() creates certain issue.. Is there any way I can communicate with you ?? Would be a great help to me.
