R Shinydashboard fileInput issue - r

Question

I refer to codes from shiny widget gallery to create a fileInput widget on my shinydashboard.
ui.R
fluidPage(
# Copy the line below to make a file upload manager
fileInput("file", label = h3("File input")),
hr(),
fluidRow(column(4, verbatimTextOutput("value")))
)
server.R
function(input, output) {
# You can access the value of the widget with input$file, e.g.
output$value <- renderPrint({
str(input$file)
})
}
I expect my app to show "file upload progress", "upload complete" status and "summary" of the file just like image below.
Below are my codes for shinydashboard:
** for your convenience, refer to "tab Item" = "file".
library(shinydashboard)
library(shiny)
# define user interface
ui <- dashboardPage(
dashboardHeader(title = "B. Times Square"),
dashboardSidebar(
sidebarMenu(
menuItem(text = "Overview", tabName = "overview", icon = icon("balance-scale-right")),
menuItem(text = "Future", tabName = "future", icon = icon("map-signs")),
menuItem(text = "History", tabName = "history", icon = icon("history")),
menuItem(text = "File Upload", tabName = "data", icon = icon("file-upload"))
)
),
dashboardBody(
tabItems(
tabItem(tabName = "overview",
fluidRow(
infoBox(title = "Revenue", 1000, icon = icon("hand-holding-usd")),
infoBox(title = "Transaction", 50, icon = icon("bed")),
infoBox(title = "Occupancy %", 40, icon = icon("percentage"))
)
),
tabItem(tabName = "future",
fluidRow(
box(
title = "Revenue [Book]", width = 4,
plotOutput(outputId = "p1-revenue-book")
),
box(
title = "Revenue [Check-In]", width = 4,
plotOutput(outputId = "p2-revenue-checkin")
),
box(
title = "RevPAR", width = 4,
plotOutput(outputId = "p3-revpar")
)
),
fluidRow(
box(
title = "Revenue [Channel]", width = 4,
plotOutput(outputId = "p4-revenue-channel")
),
box(
title = "Occupancy [unit]", width = 4,
plotOutput(outputId = "p5-occupancy")
),
box(
title = "Book vs Cancel [Unit]", width = 4,
plotOutput(outputId = "p6-book-vs-cancel")
)
)
),
tabItem(tabName = "history",
fluidRow(
box(
title = "Revenue [Check-In]", width = 4,
plotOutput(outputId = "p2-revenue-checkin")
),
box(
title = "Revenue [Book]", width = 4,
plotOutput(outputId = "p1-revenue-book")
),
box(
title = "RevPAR", width = 4,
plotOutput(outputId = "p3-revpar")
)
),
fluidRow(
box(
title = "Revenue [Channel]", width = 4,
plotOutput(outputId = "p4-revenue-channel")
),
box(
title = "Occupancy [unit]", width = 4,
plotOutput(outputId = "p5-occupancy")
),
box(
title = "Book vs Cancel [Unit]", width = 4,
plotOutput(outputId = "p6-book-vs-cancel")
)
)
),
tabItem(tabName = ***"data"***,
column(width = 4,
fluidRow(
wellPanel(
fileInput(inputId = "***csv-upload***", label = "File Upload:",
accept = c("csv", ".csv"))
)
)
)
)
)
)
)
# define server
server <- function(input, output) {
}
shinyApp(ui = ui, server = server)
I click on "Run App", tried to upload csv file but I don't see any progress bar or file upload complete status after I select a file. The widget basically doesn't work at all.
