RangeError trying to read binary .flr file

flare_flutter version: ^1.5.4

exception name: RangeError (byteOffset): Invalid value: Not in range 0..132, inclusive: 133

exception occurs in function: static Future<FlutterActor> loadFromByeData(ByteData data) -> await actor.load(data, null);

I was not having this issue until I re-exported and attempted to load my animation from the Rive editor yesterday.

sample flutter usage:

return SizedBox(
  height: 150,
  child: FlareActor(
    'assets/animations/Multiple animation test.flr',
    animation: 'idle',
  ),
);

example file:
Multiple animation test.zip

I cannot share a more complex example animation on GitHub but I can email it if necessary.

Hi @jonas-zebari, I think this is likely a version issue, could you try updating to 1.8.1 in your pubspec and see if that makes a difference?

Having very similar issues using version 1.8.1:

E/flutter ( 1752): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: RangeError (index): Invalid value: Not in range 0..13, inclusive: 14

package:flare_flutter/flare_actor.dart:263
E/flutter ( 1752): #8      FlareActor.updateRenderObject 
package:flare_flutter/flare_actor.dart:101

The error occurs when I try to cycle between these 10 flare animations but only when I either update the animation file or the animation using setState or reload using hot reload. When I change the values and then make a hot restart, everything is working fine.

I use it like this:

return FlareActor(
   fileName,
   fit: BoxFit.contain,
   alignment: Alignment.center,
   // animation is either 'in' our 'out'
   animation: animation,
);

Thanks, that helped me repro! Try flare_flutter: ^1.8.2

[jonas-zebari]

@luigi-rosso I changed my flare_flutter version to ^1.8.2 and ran packages get and got this error while running on Flutter 1.7.8+hotfix.4:

This time, the debugger stopped execution on the class AssetBundleContext in the flare.dart file. After getting that, I ran both packages get and upgrade and got this message as a compiler error instead:

For your information, I am running flutter version v1.7.8+hotfix.4. Is compatibility for flare_flutter intended for that version of Flutter? After upgrading to 1.12 stable the issue is fixed using ^1.8.2 of flare_flutter.
