Backdrop #
Transparent video animation is currently one of the more popular implementations of animation. Major manufacturers have also open sourced their own frameworks. In the end, we chose Tencent vap, which supports Android, IOS, and Web, and provides natural convenience for us to encapsulate flutter_vap. Provides a tool to generate a video with an alpha channel from a frame picture, which is simply awesome.
VAP（Video Animation Player）is developed by Penguin E-sports and is used to play cool animations.

Compared with Webp and Apng animation solutions, it has the advantages of high compression rate (smaller material) and hardware decoding (faster decoding)
Compared with Lottie, it can achieve more complex animation effects (such as particle effects)
