dispatchFunction

fun MiddlewareScope<*>.dispatchFunction(dispatch: DispatchFunction): DispatchFunction

This function only returns given dispatch. It has a few benefits over simple DispatchFunction lambda that are illustrated with this example:

fun counterMiddleware1(): Middleware<AppState> = {
   var i = restorePreviousValue() // semicolon is required here to compile
   { action -> // label must be defined manually here
      if (action is ResetCounter) {
         i = 0
         return next(action) // early exit requires a label to lambda
      }
      i++
      next(action)
   }
}

fun counterMiddleware2(): Middleware<AppState> = {
   var i = restorePreviousValue() // semicolon is NOT required here to compile
   dispatchFunction { action ->
      if (action is ResetCounter) {
         i = 0
         return@dispatchFunction next(action) // default label can be referred here
      }
      i++
      next(action)
   }
}
