Thanks! Could you add a sample json animation using this functionality as |

@calda I've updated the decoder method and added a test sample. I'm not sure why some of the tests have failed. Seems unrelated to this change. |

You have to record snapshots for the new sample animation, that's why the tests are failing :) |

I pushed a change that adds the snapshots. |

I created a .lottie animation using a third party tool and I tried to render it using lottie-ios. Unfortunately, it logged an error and didn't display the file.
However, my animation was rendering just fine in the browser. After some digging, it turns out that the the trim shape dictionary decoder requires it to have a type specified. The JavaScript implementation (and probably others) doesn't require it and sets default value when not found:
https://github.com/LottieFiles/lottie-js/blob/a1bc6c5668323161a08159a2e040ff0cf14ab46c/src/shapes/trim-shape.ts#L40
In this PR, I set default trim type to
individual. Similar to the JavaScript implementation.
