Aligned class

Aligns child content within a fixed-width column.

Use Aligned to create consistent column widths in formatted output, useful for aligning log levels, timestamps, or other fixed-width fields.

Example

// Left-align log level in 8-character column
Aligned(
  width: 8,
  align: HorizontalAlign.left,
  child: BracketedLogLevel(record.level),
)
// "[info]  " (padded to 8 chars)

// Right-align timestamp
Aligned(
  width: 12,
  align: HorizontalAlign.right,
  child: Timestamp(record.date),
)

// Center-align content
Aligned(
  width: 20,
  align: HorizontalAlign.center,
  child: PlainText('centered'),
)
// "      centered      "
