abiEncode method

  1. @override
EncoderResult abiEncode(
  1. AbiParameter params,
  2. List<int> input
)
override

Encodes a byte array to ABI-encoded bytes.

Implementation

@override
EncoderResult abiEncode(AbiParameter params, List<int> input) {
  if (params.isDynamic) {
    final parseLength = (input.length / ABIConst.uintBytesLength).ceil();
    final encoded = List<int>.filled(
        ABIConst.uintBytesLength + parseLength * ABIConst.uintBytesLength, 0);
    final number = const NumbersCoder()
        .abiEncode(AbiParameter.uint32, BigInt.from(input.length))
        .encoded;
    encoded.setAll(0, number);
    encoded.setAll(ABIConst.uintBytesLength, input);
    return EncoderResult(
        isDynamic: true, encoded: encoded, name: params.name);
  }
  final size = _ABIUtils.bytesSize(params.type);
  _ABIValidator.validateBytes(params.type,
      bytes: input, minLength: size!, maxLength: size);
  final bytes = List<int>.filled(ABIConst.uintBytesLength, 0);
  bytes.setAll(0, input);
  return EncoderResult(isDynamic: false, encoded: bytes, name: params.name);
}
