dump method

DumpedScalar dump(Object? scalar, { required int indent, int parentIndent = 0, required ScalarStyle? style, })

Dumps a scalar.

The scalar is always dumped as a flow node. Consider wrapping the scalar as a DumpableNode and overriding the NodeStyle if the style is a ScalarStyle.folded or ScalarStyle.literal.

Implementation

DumpedScalar dump(
  Object? scalar, {
  required int indent,
  int parentIndent = 0,
  required ScalarStyle? style,
}) {
  final nodeToDump = onObject(scalar);

  // Aliases here are returned "as-is".
  if (nodeToDump is DumpableAsAlias) {
    final alias = nodeToDump.dumpable;

    return (
      isMultiline: false,
      tentativeOffsetFromMargin: indent + alias.length,
      node: alias,
    );
  }

  final ConcreteNode(:dumpable, :anchor, :tag) =
      nodeToDump as ConcreteNode<Object?>;

  final (:isMultiline, :node, :tentativeOffsetFromMargin) = _dumpScalar(
    dumpable?.toString() ?? '',
    scalarStyle: style ?? defaultStyle,
    parentIndent: parentIndent,
    indent: indent,
    usePlainNull: replaceEmpty,
    forceInline: forceInline,
  );

  return (
    isMultiline: isMultiline,
    tentativeOffsetFromMargin: tentativeOffsetFromMargin,
    node: applyInline(asLocalTag(tag), anchor, node),
  );
}
