We call
Expanded(
flex: 5,
child: RiveAnimation.asset('assets/animation/pixel_ball_splash.riv'),
),

and rive crashes...

Feathering is not supported in the 0.13.x versions of the rive package. Only from 0.14.x.

See this comment to remove the clockwise fill rule: #500 (comment)

Or update to 0.14.x, please see the migration guide.
