Charts not being loaded using flexdashboard and rmarkdown (>= 1.11)

[koolmees]

Hi,

Using this simple example, I am receiving an empty screen upon opening the html document:

---
title: "Untitled"
output: 
  flexdashboard::flex_dashboard:
    orientation: columns
    vertical_layout: fill
---

```{r setup, include=FALSE}
library(flexdashboard)
```


```{r, echo = FALSE}
library("billboarder")

# data
data("prod_par_filiere")

# a bar chart !
billboarder() %>%
  bb_barchart(data = prod_par_filiere[, c("annee", "prod_hydraulique")], color = "#102246") %>%
  bb_y_grid(show = TRUE) %>%
  bb_y_axis(tick = list(format = suffix("TWh")),
            label = list(text = "production (in terawatt-hours)", position = "outer-top")) %>% 
  bb_legend(show = FALSE) %>% 
  bb_labs(title = "French hydraulic production",
          caption = "Data source: RTE (https://opendata.rte-france.com)")
```

The people from rmarkdown were able to find the following:

This only happens with rmarkdown versions 1.11 and onwards. Could you please look into this from the JS side of things, to identify what causes this issue to happen?

Possible more information in my original topic: rstudio/rmarkdown#2378

Sorry for late answer but I have no idea why this isn't working with this specific widget. I think this is CSS related..
I corrected the error you mentionned, but no positive effect.

Ok I still don't know why the graphics don't render but I found a workaround, it should work now. Please re-install from GitHub.
