# Snackbar

Material Design 3 snackbar component for brief notifications.

## Basic Usage

```rust
use bevy_material_ui::prelude::*;
use bevy_material_ui::snackbar::{ShowSnackbar, SnackbarHostBuilder};

fn setup(mut commands: Commands, theme: Res<MaterialTheme>) {
    // Add snackbar host to your UI root
    SnackbarHostBuilder::new()
        .spawn(&mut commands, &theme);
}

// Show a snackbar
fn show_notification(
    mut writer: MessageWriter<ShowSnackbar>,
) {
    writer.write(ShowSnackbar::message("Operation completed"));
}
```

## With Action

```rust
fn show_with_action(
    mut writer: MessageWriter<ShowSnackbar>,
) {
    writer.write(
        ShowSnackbar::with_action("File deleted", "UNDO")
    );
}
```

## Custom Duration

```rust
use bevy_material_ui::snackbar::SnackbarDuration;

fn show_custom_duration(
    mut writer: MessageWriter<ShowSnackbar>,
) {
    // Short duration (4 seconds)
    writer.write(
        ShowSnackbar::message("Quick message")
            .duration(SnackbarDuration::Short)
    );

    // Long duration (10 seconds)
    writer.write(
        ShowSnackbar::message("Important message")
            .duration(SnackbarDuration::Long)
    );

    // Indefinite (stays until dismissed)
    writer.write(
        ShowSnackbar::message("Persistent message")
            .duration(SnackbarDuration::Indefinite)
    );
}
```

## Handling Action Clicks

```rust
use bevy_material_ui::snackbar::SnackbarActionEvent;

fn handle_snackbar_action(
    mut reader: EventReader<SnackbarActionEvent>,
) {
    for event in reader.read() {
        if event.action_label == "UNDO" {
            println!("Undo action triggered!");
            // Perform undo logic
        }
    }
}
```

## Multiple Snackbars

Snackbars queue automatically. When one is dismissed, the next appears.

```rust
fn show_multiple(
    mut writer: MessageWriter<ShowSnackbar>,
) {
    writer.write(ShowSnackbar::message("First message"));
    writer.write(ShowSnackbar::message("Second message"));
    writer.write(ShowSnackbar::message("Third message"));
}
```
