There is LottieCache in lottie_provider.dart. can i clear the Cache after page disposed?

Hi, This is a good feature request. There is still some work to do with cache management (pre-cache is on the list too).

As of now, you have to import a private file:

import 'package:lottie/src/providers/lottie_provider.dart' show sharedLottieCache;

main() {
  sharedLottieCache.clear();
}

This is a temporary hack that may not work in the future.

Otherwise, you can also not use Lottie.asset and Lottie.network and do the loading/caching yourself: See: https://github.com/xvrh/lottie-flutter/blob/master/example/lib/examples/custom_load.dart

sharedLottieCache.clear();

i had try this, but Memory reduction is very limited, seems json or image not release.

imageProvider?.evict()
