show method

void show(String text, { ToastType type = ToastType.success, ToastDurationType durationType = ToastDurationType.short, Icon? icon, })

Displays a toast with the given text.

Optional parameters:

• type: Determines icon and color styling. Default is ToastType.success.
• durationType: Determines how long the toast stays visible.
• icon: Custom icon. If null, a default icon is used based on type.

If another toast is already visible, this call will be ignored.

Implementation

void show(
  String text, {
  ToastType type = ToastType.success,
  ToastDurationType durationType = ToastDurationType.short,
  Icon? icon,
}) {
  if (!_context.mounted) return;

  final overlay = Overlay.maybeOf(_context);
  if (overlay == null) return;

  // Prevent showing multiple toasts at once.
  if (_currentToast != null) return;
  _currentToast = this;

  _overlayEntry = OverlayEntry(
    builder: (context) => Positioned(
      bottom: 40,
      left: 20,
      right: 20,
      child: Material(
        color: Colors.transparent,
        child: _buildToastContent(context, text, type, durationType, icon),
      ),
    ),
  );

  overlay.insert(_overlayEntry!);

  Future.delayed(
    Duration(seconds: durationType == ToastDurationType.short ? 4 : 8),
    _removeToast,
  );
