parseArguments static method

List<AptosEntryFunctionArguments> parseArguments({ required AptosApiMoveFunction function, required List<Object?> values, List<AptosTypeTag> genericTypeArgs = const [], })

Parses the provided dynamic values into a list of AptosEntryFunctionArguments that match the expected argument types of the given function.

• function: The Aptos Move function definition containing metadata about expected argument types.
• values: The actual argument values to be parsed and converted.
• genericTypeArgs: Optional list of generic type arguments (type tags) to handle generic Move functions.

Returns a list of AptosEntryFunctionArguments ready for transaction execution.

Implementation

  required AptosApiMoveFunction function,
  required List<Object?> values,
  List<AptosTypeTag> genericTypeArgs = const [],

    (e) => e != "&signer" && e != "signer",
  );
  List<String> paramsString = function.params;
  if (signerIndex >= 0) {
    paramsString = paramsString.sublist(signerIndex);
  }
  final tags =
      paramsString
          .map((e) => AptosFunctionEntryArgumentUtils.parseTag(e))
          .toList();
  if (tags.length != values.length) {
    throw DartAptosPluginException(
      "Mismatch between parameters and values: expected ${tags.length} parameters, but got ${values.length} values.",
    );
  }

  return List.generate(tags.length, (index) {
    final type = tags[index];
    final value = values[index];
    try {
      return type.toEntryFunctionArguments(
        value: value,
        genericTypeArgs: genericTypeArgs,
      );
    } catch (e) {
      throw DartAptosPluginException(

        details: {"message": e.toString(), "type": type, "value": value},
