This issue is also present on simolus3#240

full error :
rpc error "Unhandled Exception: RPCError: got code -32700 with msg "Invalid signature v value"

steps to reproduce :
sign any contract transaction and try to send the transaction
expected : it should be ok
result : it fails with rpc error "Unhandled Exception: RPCError: got code -32700 with msg "Invalid signature v value"

I solved the problem by manually optaning the chain_id and supply it while sending the transaction.

Thank you, you are a lifesaver.
Here is the code that you are referring to:

BigInt cId = await _client.getChainId();
    await _client.sendTransaction(_credentials,
        Transaction.callContract(contract: _contract, function: _addPerson, parameters: [_credentials.address]),chainId: cId.toInt());
