How to include a png file in R flexdashboard - png

Question

Could you please help me in finding the right code to print a png image inside a R flexdashboard?
Here my code chunk:
---
title: "Analyse des installations PV - Les Vergers"
author: "Dario Santandrea"
date: "`r format(Sys.time(), '%d %B, %Y')`"
output:
flexdashboard::flex_dashboard:
orientation: rows
vertical_layout: fill
runtime: shiny
---
First attempt
renderImage({
outfile <- tempfile(fileext = "X:/LesVergers/Analyse/BilanSolaire/Figures/Solar_angle_scheme.png")
png(outfile, width = 500, height = 400)
dev.off()
}
)
Second attempt
#knitr::include_graphics("X:/LesVergers/Analyse/BilanSolaire/Figures/Solar_angle_scheme.png")
The image i've been trying to print doesn't simply appear in the flexdashboard

flexdashboard is essentially Markdown. Thus see e.g. this related thread.
```{r picture, echo = F, fig.cap = "Title", out.width = '100%'}
knitr::include_graphics("picture.png")
```
Just place this chunk within the standard flexdashboard layout:
BLOCK1
=====================================
Row {data-width=1000}
-----------------------------------------------------------------------
### A picture
```{r picture, echo = F, fig.cap = "Title", out.width = '100%'}
knitr::include_graphics("picture.png")
```
