This is why:
airbnb/lottie-android#1177

This plugin is using an old version of the player.

Using Old version JSON didn't fixed the issue either? Can anyone confirm which version of bodymovin works?

[ParsaGachkar]

@CameronStuartSmith Can you confirm which version of bodymovin was used for generating example Animations?

[DanialV]

Please update lottie version to > 3.0 to fix this issue

I updated lottie version in flutter_lottie/android/build.gradle so as temporary solution you can use my repository and add to your pubspec.yaml next lines:

dependencies:
  flutter_lottie:
    git:
      url: https://github.com/RenatFakhrutdinov/flutter_lottie.git

Hi,
Thanks for the temporary solution. How can I solve the problem permanent?
Thanks

@MrHazee Hi!
This lib isn't updated for a long time.
Try to use https://pub.dev/packages/lottie
