transfer_icp function

Future<Variant> transfer_icp(Caller caller, String fortheicpid, IcpTokens mount, { IcpTokens? fee, Nat64? memo, List<int>? subaccount_bytes, })

Returns the Variant response of this call - the Result<Ok, Err> variant. Check the ICP ledger's candid service file for the specific structure of this variant response to this call.

    subaccount_bytes ??= Uint8List(32);
    if (subaccount_bytes.length != 32) { throw Exception(': subaccount_bytes-parameter of this function is with the length-quirement: 32-bytes.'); }
