# Snackbar

### Overview

Snackbars provide quick, unobtrusive messages that can include an action button. Useful for showing brief messages at the bottom of the screen.

The `snackbar` modifier allows you to present a Material Design styled snackbar with a message, optional duration, and action button. You can configure the snackbar to fit your needs by specifying its duration and providing an action for the user.

To use the `snackbar` modifier, apply it to any View with the required parameters. 

### Modifers

```swift
snackbar(isPresented: Binding<Bool>, message: String)
```

snackbar(
    isPresented: Binding<Bool>,

    action: (() -> Void)?
