getValue method

Implementation

dynamic getValue(Name node) {
  // 1) Try the node's own scope first (captures nested function declarations).
  if (node.scope != null) {
    final Context scopedCtx = getContextForScope(node.scope!);
    final dynamic fromScoped = scopedCtx.getContextById(node.value);
    if (fromScoped != null) return fromScoped;
  }

  // 2) Scan all known contexts (newest first) as a safety net.
  for (final Scope s in contexts.keys.toList().reversed) {
    final dynamic v = contexts[s]!.getContextById(node.value);
    if (v != null) return v;
  }

  // 3) Fallback to the resolved scope via environment tracking.
  Scope scope = findScope(node);
  Context ctx = getContextForScope(scope);
  return ctx.getContextById(node.value);
}
