I provided an image of the code I already have, but how do I make it in descending order?

I provided an image of the code I already have, but how do I make it in descending order?

 
    
     
    
    df <- data.frame(
  stringsAsFactors = FALSE,
          type = c('Ave', 'Blvd', 'Cirle', 'Court', 'Dr'),
              total = c(254, 25, 30, 35, 550)
)
ggplot(data = df, 
       mapping = aes(x = fct_reorder(type, total),  y = total)) +
  geom_bar(stat = 'identity', fill = '#112446')+
  theme_bw()
add .desc = TRUE to fct_reorder for descending
ggplot(data = df, 
       mapping = aes(x = fct_reorder(type, total,  .desc = TRUE),  y = total)) +
  geom_bar(stat = 'identity', fill = '#112446')+
  theme_bw()
