First I have the code that creates a flexadashboard. When the user selects a button the relative pop-up message is enabled. As you can see everything happens inside a renderUI() object. The issue is that I do not know how to create the same result within a shiny app since I cannot use the renderUI() like this inside the server.r part.

title: "Single Column (Fill)"
output:
flexdashboard::flex_dashboard:
vertical_layout: fill
runtime: shiny

### Chart 1
```{r}
library(flexdashboard)
library(shiny)
library(shinyWidgets)
radioButtons("radio", label = h3("Radio buttons"),
choices = list("Choice 1" = 1, "Choice 2" = 2, "Choice 3" = 3),
selected = 1)
renderUI({
if (input$radio==1) {
#paste("The following tickers already exist in the database:", bad_tickers, collapse = " ")
sendSweetAlert(session, title = "Bad tickers", text = paste("The following tickers already exist in the database:"))
} else if (input$radio==2) {
#paste("The following names already exist in the database:", bad_names, collapse = " ")
sendSweetAlert(session, title = "Bad Names", text = paste("The following names already exist in the database:"))
}
else {
sendSweetAlert(session, title = "Nice!", text = "Your tickers, names and weights have been saved. You'll see them appear as available funds if you refresh your browser.")
}
})
```
library(shiny)
library(shinyWidgets)
ui <- fluidPage(
tags$h2("Sweet Alert examples"),
radioButtons("radio", label = h3("Radio buttons"),
choices = list("Choice 1" = 1, "Choice 2" = 2, "Choice 3" = 3),
selected = 1)
)
server <- function(input, output, session) {
sendSweetAlert(
session = session,
title = "1",
text = "All in order",
type = "success"
)
sendSweetAlert(
session = session,
title = "2",
text = "It's broken...",
type = "error"
)
sendSweetAlert(
session = session,
title = "3",
text = "Non exist...",
type = "error"
)
}
shinyApp(ui, server)
If you want to translate your flex dash board into shiny, just create an actual uiOutput object in your layout and render it in the server function. (renderUI is a shiny function as well.)
library(shiny)
library(shinyWidgets)
ui <- fluidPage(
tags$h2("Sweet Alert examples"),
radioButtons("radio", label = h3("Radio buttons"),
choices = list("Choice 1" = 1, "Choice 2" = 2, "Choice 3" = 3),
selected = 1),
uiOutput("result")
)
server <- function(input, output, session) {
output$result <- renderUI({
if (input$radio==1) {
#paste("The following tickers already exist in the database:", bad_tickers, collapse = " ")
sendSweetAlert(session, title = "Bad tickers", text = paste("The following tickers already exist in the database:"))
} else if (input$radio==2) {
#paste("The following names already exist in the database:", bad_names, collapse = " ")
sendSweetAlert(session, title = "Bad Names", text = paste("The following names already exist in the database:"))
}
else {
sendSweetAlert(session, title = "Nice!", text = "Your tickers, names and weights have been saved. You'll see them appear as available funds if you refresh your browser.")
}
})
}
shinyApp(ui, server)
