Lottie

LVGL v8

LVGL v8 doesn't natively support Lottie animations. It supports Lottie via 3rd-party library. Please refer to rlottie integration for more details.

We integrated library of rlottie into anyui, so you can leverage the generated code and simulate Lottie animations thru anyui, but you still need to do rlottie integration for your target device.

LVGL v9

Starting from v9, The Lottie widget uses the ThorVG library which is integrated into LVGL. In order to use Lottie animations LV_USE_THORVG_INTERNAL (to use the built-in ThorVG) or LV_USE_THORVG_EXTERNAL (to link it externally) needs to enabled, so you can directly use Lottie animations in LVGL v9.

anyui uses built-in ThorVG for Lottie, and is abled to simulate Lottie animations on simulator.

For more details please refer to Lottie of LVGL v9.
