AlertDialogHelper class

A common alert dialog function that provides a reusable way to show alert dialogs with customizable icon, text constraints, markdown content, and flexible button options.

Usage Examples:

Basic usage with auto-sizing (no constraints):

ui.AlertDialogHelper.showWarning(
  context: context,
  markdownText: '**Warning!** This action cannot be undone.',
  onConfirm: () => print('Confirmed'),
  // Dialog will automatically size to fit content
);

Centered text with custom constraints:

ui.AlertDialogHelper.showInfo(
  context: context,
  markdownText: '**Centered Information**\n\nThis text is centered.',
  textAlignment: TextAlign.center,
  textConstraints: BoxConstraints(
    minWidth: 400.0,
    maxWidth: 600.0,
    minHeight: 200.0,
    maxHeight: 500.0,
  ),
);

Full width dialog that fills available space:

ui.AlertDialogHelper.showWarning(
  context: context,
  markdownText: '# Full Width Dialog\n\nContent that fills the space.',
  textConstraints: BoxConstraints(
    minWidth: 500.0,
    maxWidth: 800.0,
    minHeight: 300.0,
    maxHeight: 600.0,
  ),
  textAlignment: TextAlign.center,
);

Compact dialog with minimal space:

ui.AlertDialogHelper.showError(
  context: context,
  markdownText: '**Compact Error**\n\nMinimal constraints.',
  textConstraints: BoxConstraints(
    minWidth: 200.0,
    maxWidth: 300.0,
    minHeight: 50.0,
    maxHeight: 150.0,
  ),
);
