Use Lottie in Flutter.
Supports most features that both iOS and Android support.
The only dynamic property changing that is supported for now is color and opacity. Project will be updated later to include support for other properties.
Example in the github repo includes a good intro into using the library.
To use with iOS, you will need to add this key to your info.plist file located in: project/ios/Runner/Info.plist
<key>io.flutter.embedded_views_preview</key> <true />
This repo is forked from mark922/flutter_lottie and add some basic feature on it
