Rive factory does not repaint when app comes from background.

[gabrielgarciagava]

Description

Moving the app to the foreground will leave a black screen where the image/animation should be.
This issues only happens when:

1. Using Rive factory. (File.asset("assets/vehicles.riv", riveFactory: Factory.rive))
2. The animation is static when foregrounding.

Tested with Rive 0.14.0-dev.8

Steps To Reproduce

Steps to reproduce the behavior:

1. Build a File using some animation that is not looping (so that it stays still at some point) and rive Factory
2. Build a RiveWidgetController and RiveWidget using such File
3. Background the app when the image is static
4. Foreground the app. A blank screen will be shown

Notes:
If the animation is ongoing/looping, the issue does not happen.
If the flutter factory is used, the issue does not happen.
As a workaround, calling controller.scheduleRepaint() when didChangeAppLifecycleState is called with AppLifecycleState.resumed fixes the problem.
