How to add Lottie or Rive to a Flutter app

For Lottie, add the pure-Dart lottie package (3.6.x) and call Lottie.asset() or Lottie.network(); dotLottie files work through a custom loader. For Rive, add the rive package (0.14.x), which depends on rive_native and offers both the Rive and Flutter renderers on every platform.
