How to make a block's item drop/item entity resistant to fire/lava?

I asked an AI model for an example (embarrassing, I know) and it spat this out - no testing has been done, but does this work? Any experts here? I doubt it, somehow, lol.

@Override
	public ItemStack getCloneItemStack(BlockGetter world, BlockPos pos, BlockState state) {
        ItemStack stack = new ItemStack(this.asItem());
        stack.fireResistant(); // Makes the dropped item fire-resistant
        return stack;
    }

    public static class FireResistantBlockItem extends BlockItem {
        public FireResistantBlockItem(Block block) {
            super(block, new Item.Properties().fireResistant());
        }
	}
