Hey.
I'm having trouble parsing my Flare file in the flutter: I get a weird error The method '[]' was called on null.
Flutter code:
child: FlareActor(
"resources/animations/animated_house.flr",
animation: "Enter transition",
),
Stacktrace:
[ERROR:flutter/shell/common/shell.cc(184)] Dart Error: Unhandled exception:
NoSuchMethodError: The method '[]' was called on null.
Receiver: null

Flutter file:

Also, I have noticed that in preview door doesn't get opened as they get opened inside of a Flare editor. I have tried exporting .flr file as Binary and JSON format.
Thanks for reporting. I think this was due to an out of sync package on pub. We just published an update.
Make sure you're using the latest flare_flutter (^1.0.3) in your pubspec. You could also pub upgrade flare_flutter.
Let me know if that helps.
Thanks for the quick reply. I have tried your suggestion but with no luck. I'm now using ^1.0.3 version and I've also tried to update with pub upgrade but I'm stuck with the same error as before.
You can check the content of animated_house.flr file here: https://jsoneditoronline.org/?id=a3ec501c58264ad1b0149aa6444df17b
Is there maybe some operation that is not supported by flare_flutter package?
