Pulldown refresh loading - Nationwide purchase

Guys, this is the project I did at the company last year. This animation is applied to the drop-down refresh of the app homepage.
In order to convey to the user the new business of buying car and logistics in the whole country, I designed this creative animation.
The implementation method is Airbnb's open source project Lottie, which makes the animation a vector graphic while also greatly reducing the size. Makes a better performance and experience in the app.
In addition, I also added the interactive effects of the drop-down gestures on the online effect.
Hope you like it.
