ConstantInfo? getConstantInfo(String palletName, String constantName)

Get constant metadata information

Returns information about a constant without decoding its value

Implementation

ConstantInfo? getConstantInfo(String palletName, String constantName) {
  final pallet = registry.palletByName(palletName);
  if (pallet == null) return null;

  final constant = pallet.constants.firstWhere(
    (c) => c.name == constantName,
    orElse: () =>
        throw MetadataException('Constant $constantName not found in pallet $palletName'),
  );

  final type = registry.typeById(constant.type);

  return ConstantInfo(
    name: constant.name,
    type: type,
    typeId: constant.type,
    value: Uint8List.fromList(constant.value),
    docs: constant.docs,
    palletName: palletName,
  );
