VAlert class

A customizable alert component that displays important messages with an icon, title, and optional subtitle.

VAlert provides a flexible way to show alerts to users with different visual styles and sizes. It supports two variants (primary and destructive) and three size options (small, medium, large). The component automatically adjusts typography and icon sizes based on the selected size.

The widget uses two enums for configuration:

  • VAlertVariant: Controls alert style and color (primary, destructive)
  • VAlertSize: Controls overall alert size affecting title, subtitle, and icon sizes (small, medium, large)

Parameters:

  • icon: The icon data to display (required)
  • title: The main alert message (required)
  • subtitle: Optional secondary message displayed below the title
  • variant: The alert style variant (defaults to primary)
  • size: The alert size (defaults to medium)
  • borderless: Whether to remove the border decoration (defaults to false)

Example:

VAlert(
  icon: Icons.warning,
  title: 'Payment Failed',
  subtitle: 'Your transaction could not be processed',
  variant: VAlertVariant.destructive,
  size: VAlertSize.large,
)
