tested...

public static final DeferredRegister FLUID_TYPES = DeferredRegister.create(ForgeRegistries.Keys.FLUID_TYPES, testmod.MODID);
public static final DeferredRegister FLUIDS = DeferredRegister.create(ForgeRegistries.FLUIDS, testmod.MODID);

}
public static final RegistryObject LAVA_TYPE = FLUID_TYPES.register("lava",
() -> new FluidType(FluidType.Properties.create().lightLevel(5).density(1024).viscosity(1024).pathType(BlockPathTypes.LAVA).adjacentPathType(BlockPathTypes.DANGER_OTHER).sound(SoundActions.BUCKET_EMPTY, ACSoundRegistry.ACID_UNSUBMERGE.get()).sound(SoundActions.BUCKET_FILL, ACSoundRegistry.ACID_SUBMERGE.get())));
public static final RegistryObject LAVA = FLUIDS.register("lava",
() -> new ForgeFlowingFluid.Source(lavaProperties()));
public static final RegistryObject LAVA_FLOWING = FLUIDS.register("lava_flowing",
() -> new ForgeFlowingFluid.Flowing(lavaProperties()));

public static void register(IEventBus eventBus) {
FLUIDS.register(eventBus);
}
