equals method

@override bool equals(FluentNode other, { bool ignoreSpans = true, })

Structural equality.

When ignoreSpans is true (the default), two ASTs from differently- positioned sources compare equal as long as their structure matches — useful for testing parser output against expected shapes regardless of whitespace placement. Set false for a strict, position-aware comparison that requires every Span to match.

Implementation

@override
bool equals(FluentNode other, {bool ignoreSpans = true}) {
  if (other is! NumberLiteralExpression) return false;
  if (!literal.equals(other.literal, ignoreSpans: ignoreSpans)) return false;
  return _spansEqual(span, other.span, ignoreSpans: ignoreSpans);
}
