How to use the SnackBar?

[rabejens]

I found a MudSnackBarProvider' which I added in my view function. Now, how do I post things to the SnackBar when an event happens? Do I have to get an ISnackBar via html.inject and hand it down through my view functions or is there a more Fun.Blazorish way?

I normally just use html.inject to wrap every components which need services like ISnackBar, IComponentHook etc.

I did it this style. I added MudSnackbarProvider' and injected an ISnackbar. Then, I prepare functions posting my desired mesages to the snackbar beforehand, prepare update functions with these as parameters and use Cmd.OfFunc.attempt to call them.

Example:

let update reportOnSnackbar msg state =
    match msg with
    | AddFiles files ->
        let filesToAdd = files |> Seq.filter(fun f -> state.files |> List.contains f |> not) |> Seq.toList
        let cmd = Cmd.OfFunc.attempt reportOnSnackbar (sprintf "%d file%s added" filesToAdd.Length (if filesToAdd.Length = 1 then "" else "s")) Failed
        { state with files = List.append filesToAdd state.files }, cmd
    // more...
