Latest version - NoSuchMethodError: The method '*' was called on null.

[RaviKavaiya]

Hello, I am using the latest version of flare_flutter 1.3.0
Reference code : https://github.com/tarek360/Boring-Star-Animation (all same, but version 1.3.0)
The code works fine out of the box, but when I changed the animation, it displayed, but a still image (not a moving animation)
And, this was the error :

E/flutter (24934): [ERROR:flutter/lib/ui/ui_dart_state.cc(148)] Unhandled Exception: NoSuchMethodError: The method '*' was called on null.

EDIT : I used both binary and json formats, but no luck :(

EDIT 2 : I used below animation and is WORKING fine :

I don't know what is the problem with my animation :(

Thanks for reporting, I'll look into this today and report back.

[luigi-rosso]

I've just pushed an updated flare_flutter 1.3.1 which should fix this issue. Please try it out and let me know!

[RaviKavaiya]

Thanks for the update. I will check it as soon as possible as I get free and report back

[RaviKavaiya]

@luigi-rosso I tried the same animation with version 1.3.2. No, the problem is not resolved.
I wonder that there must be a problem with my animation. What do you say?

[umberto-sonnino]

Hey @RaviKavaiya, we investigated this a bit further and it appears to be a combination of both!
You set your Trim Path keys for the Check shape in your animation, and then you set Trim Path to Off afterwards.
So you can circumvent the issue right now by setting instead to Sequential
We're working on a fix in the meantime!

[RaviKavaiya]

@umberto-sonnino OK, I set it to Sequential and it works fine.
