showWarningSnackBar static method

void showWarningSnackBar(
  1. String message, {
  2. String title = "",
  3. Function? onDismiss,
})

Displays an awesome-styled warning snackbar with optional dismiss callback.

Shows a visually rich warning snackbar at the bottom of the screen using the AwesomeSnackbarContent widget. The snackbar automatically unfocuses active text fields and can trigger a callback when dismissed.

Parameters:

  • message: The warning message to display (required, skips if empty)
  • title: Custom title (defaults to "Warning" if empty)
  • onDismiss: Optional callback function triggered when snackbar closes

The snackbar features:

  • Orange background color (warning theme)
  • Small font size from app theme
  • Bottom position with floating style
  • Smooth ease-in/ease-out animations
  • Duration from app constants (snackbarDuration)
  • Dismissible by user interaction

Example:

RtCommonFunction.showWarningSnackBar(
  'Please verify your email',
  title: 'Account Warning',
  onDismiss: () => print('Warning dismissed'),
);
