Flare animations not visible in release/profile build mode

[anisalibegic]

Hi all,

I'm having a problem where some Flare animations are invisible in release or profile mode.

This one is visible
This one is invisible

I really don't know what to do in this situation. Maybe the squares loader animations is wrong in some way?

I'm using flare_flutter: ^1.5.0.

Anybody knows why this occurs?

It's an issue with v1.5.4-hotfix.2, if you upgrade to something newer you'll see it's gone. It's unfortunate that it's the current stable build.

[anisalibegic]

I tried changing to master channel but there was a breaking change flutter/flutter#31962 and half of my packages are failing to build... any other way?

[luigi-rosso]

There's a breaking change on both dev and master with one of the APIs that Flare uses. Unfortunately we have to keep the version on pub compatible with stable. To use a more bleeding edge version, point your pubspec to our github:

flare_flutter:
  git: 
    url: git://github.com/2d-inc/Flare-Flutter.git
    ref: dev
    path: flare_flutter

Just be aware that dev is a moving target, if you want to be keep it compatible with a specific version of master you are on, reference the current dev tree instead:

flare_flutter:
  git: 
    url: git://github.com/2d-inc/Flare-Flutter.git
    ref: c51192dec50dec034d121f6aad7d2e8733c7e279
    path: flare_flutter

That'll allow Flare to work with newer Flutter versions, you may need to do something similar for the other packages.

I got stuck on AndreHaueisen/flushbar#44 (comment) and it prevents me from staying on master channel... Why some of the animations are working correctly and some are not?

[anisalibegic]

Changed Flutter channel to master and version 1.5.9, changed the source of the flare_flutter to GitHub instead of pub.dev, fixed errors in other packages, successfully built the app... still no animations.

[luigi-rosso]

That's frustrating, sorry for the trouble. Lots of things changed this week so quite a few of them are still settling.

Are you seeing no animations in release/profile or no animations in debug as well?

[anisalibegic]

I have two animations side by side. The one your brother made and the one I made. When I run my application in the debug mode I can see both animations but in the release/profile mode all I can see is your brother's animation.

[luigi-rosso]

It really sounds like this issue: #87

I thought this had been fixed right after hotfix.2, but it sounds like it's still a problem. It sounds like flutter 1.2.1 with flare_flutter 1.5.0 (from pub) should work together. In the meantime I'll make sure we open an issue with the main flutter repository too.

I'm having the same problem.
I am currently on Flutter version 1.5.4-hotfix.2 and flare_flutter: ^1.5.0 and my animation is not showing in release mode, only in debug mode.

[luigi-rosso]

Can the people who were able to reproduce this issue please give it a try on the latest flutter master or dev channel? You'll need to point your pubspec to our flare dev:

flare_flutter:
  git: 
    url: git://github.com/2d-inc/Flare-Flutter.git
    ref: dev
    path: flare_flutter

And you'll need to use flutter dev or master:

flutter channel master
flutter upgrade

Confirmed that animations are working in release/profile mode while using Flutter 1.7.6-pre.41 • channel master and flare_flutter git:dev.
