render method

@override void render(Buffer buffer, Rect area)

Renders the widget onto the provided buffer within the specified area.

Implementation

@override
void render(Buffer buffer, Rect area) {
  if (bounds.width <= 0 || bounds.height <= 0) return;

  // 1. Check/force focus to modal if it got lost/not set
  bool anyFocused = false;
  for (final node in modalFocusNodes) {
    if (node.isFocused) {
      anyFocused = true;
      break;
    }
  }
  if (!anyFocused && modalFocusNodes.isNotEmpty) {
    modalFocusNodes.first.requestFocus();
  }

  // 2. Draw the background scrim (dimming the cells beneath the modal)
  for (var y = 0; y < bounds.height; y++) {
    for (var x = 0; x < bounds.width; x++) {
      final cell = buffer.getCell(bounds.x + x, bounds.y + y);
      if (cell != null) {
        final isInsideDialog =
            x >= dialogBounds.x &&
            x < dialogBounds.x + dialogBounds.width &&
            y >= dialogBounds.y &&
            y < dialogBounds.y + dialogBounds.height;
        if (!isInsideDialog) {
          cell.style = Style(
            foreground: cell.style.foreground,
            background: cell.style.background,
            modifiers: cell.style.modifiers | Modifier.dim,
          );
        }
      }
    }
  }

  // 3. Draw the central dialog box inside dialogBounds
  final originalBounds = bounds;
  bounds = dialogBounds;
  super.render(buffer, area);
  bounds = originalBounds;
