updateSelected method

void updateSelected(List<bool> newSelection, bool enableHapticFeedback)

Updates the selection state for multiple items in a batch operation.

This method is optimized for drag selection operations where multiple items may change state simultaneously. It provides several advantages over individual toggle calls:

Features

• Batch Processing: Updates all items in a single operation
• Change Detection: Only processes items that actually changed
• Haptic Feedback: Optional tactile feedback for state changes
• Single Notification: Notifies listeners once after all updates

Haptic Feedback

When enableHapticFeedback is true, provides subtle vibration feedback for each item whose selection state changes. This enhances user experience during drag selection by providing tactile confirmation of selections.

Performance

More efficient than multiple toggle calls because:

• Single listener notification instead of per-item notifications
• Early exit for unchanged items
• Direct list assignment without bounds checking per item

Implementation

void updateSelected(List<bool> newSelection, bool enableHapticFeedback) {
  for (int i = 0; i < newSelection.length; i++) {
    if (newSelection[i] != _selected[i]) {
      _selected[i] = newSelection[i];
      if (enableHapticFeedback) {
        HapticFeedback.lightImpact();
      }
    }
  }
  notifyListeners();
}
