Cannot investigate, so I'm just capturing.
In this state (after the first task got completed and after I tapped to add a new task):
I got this assertion error

It's an assertion, so won't show up in production, but it definitely signifies something fishy. Especially since it's thrown from dart:ui/painting.dart. Unfortunately, the exact line is optimized out (even though we're in debug mode, which is a surprise to me).

For completeness:
this happens on current head (1171d65) and with Flutter 1.5.4 • channel dev.

Thanks for reporting this. I have a fix incoming with the next Flare update, I'll update the dependency in my next PR.

Hi
The number here withOpacity(N) must be between 0 and 1
