file

This factory generates a single file selection context.

In there you can create a button with a label, an icon, the position of the icon and access its events. For a detailed overview about the possible properties of the button component object itself, have a look at PushButtonComponent

The File function then returns a Flow of File in order to combine the Flow directly to a fitting handler which accepts a File:

val textFileStore = object : RootStore<String>("") {
    val upload = handle<File> { _, file -> file.content }
}
file {
  accept("text/plain")
  encoding("utf-8")
  button(id = "myFile") {
    text("Select a file")
  }
} handledBy textFileStore.upload

Return

a Flow that offers the selected File
