```dart
// Basic truncation
WText(
  'Long text that should be truncated...',
  className: 'truncate',
)

// Limit to specific lines
WText(
  'Multi-line text block...',
  className: 'line-clamp-3',
)
```

## Basic Usage

Use `truncate` to prevent text from wrapping and truncate overflowing text with an ellipsis (...) if needed. This is the most common way to handle overflow for single-line text.

```dart
WDiv(
  className: 'w-64',
  child: WText(
    'The quick brown fox jumps over the lazy dog.',
    className: 'truncate',
  ),
)
```

## Quick Reference

| Class | Properties | Description |
|:------|:-----------|:------------|
| `truncate` | `maxLines: 1`, `softWrap: false`, `overflow: ellipsis` | Truncate text with an ellipsis on a single line. |
| `text-ellipsis` | `overflow: ellipsis` | Use an ellipsis for overflow. |
| `text-clip` | `overflow: clip` | Clip overflowing text (no ellipsis). |
| `line-clamp-{n}` | `maxLines: n`, `overflow: ellipsis` | Limit text to n lines. |
| `line-clamp-none` | `maxLines: null` | Remove line limits. |

## Truncate

The `truncate` utility is a shorthand that sets three properties at once:
1. Sets `maxLines` to 1
2. Disables `softWrap`
3. Sets `overflow` to `TextOverflow.ellipsis`

```dart
WText(
  'Long text that will be cut off with an ellipsis if it gets too long',
  className: 'truncate',
)
```

## Ellipsis & Clip

Use `text-ellipsis` or `text-clip` to control the visual overflow behavior specifically.

- **text-ellipsis**: Renders an ellipsis (...) when text overflows.
- **text-clip**: Simply cuts off the text at the boundary.

```dart
// Ellipsis (default for truncate/line-clamp)
WText('...', className: 'text-ellipsis')

// Clip (hard cut)
WText('...', className: 'text-clip')
```

## Line Clamp

Use `line-clamp-{n}` to limit text to a specific number of lines. This automatically sets the overflow style to ellipsis.

Supported values are any integer number (e.g., `line-clamp-2`, `line-clamp-5`) and `line-clamp-none`.

```dart
WText(
  'This is a long paragraph that needs to be clamped to a specific number of lines...',
  className: 'line-clamp-3',
)

// Resetting line clamp
WText(
  '...',
  className: 'line-clamp-3 lg:line-clamp-none',
)
```

## Responsive Design

Apply different overflow utilities at different breakpoints using standard responsive prefixes.

```dart
// Truncate on mobile, allow wrapping on desktop
WText(
  'Responsive text behavior...',
  className: 'truncate md:whitespace-normal',
)

// 2 lines on mobile, 4 lines on tablet, unlimited on desktop
WText(
  'Responsive line clamping...',
  className: 'line-clamp-2 md:line-clamp-4 lg:line-clamp-none',
)
```

## Dark Mode

While overflow utilities don't visually change in dark mode, you can still apply them conditionally using the `dark:` prefix if your design requires different text handling in dark mode.

```dart
WText(
  '...',
  className: 'truncate dark:line-clamp-2',
)
```

## Arbitrary Values

> [!NOTE]
> Arbitrary values (bracket syntax) are not currently supported for `text-` overflow or `line-clamp-` utilities.
>
> `line-clamp-{n}` supports any integer number directly (e.g., `line-clamp-7`), so bracket syntax is generally not needed.

## Customizing Theme

These utilities do not use theme variables. `line-clamp` accepts numeric values directly, and overflow types are static.
