client.sendTransaction not tranferring any ether in private chain

[brothereum]

Hi, I am very new to web3dart or blockchain. I have some problem with web3dart, I am unable to send transaction using the dart code attached in this issue. The code executed correctly however it is not transferring any amount. It returned a transaction hash however whenever I checked it in the metamask transactions does not show up neither value changes. It may be due to non specifying a network_id or hardfork along with the transaction. The code equivalent that work correctly in the web3js is also attached.

//Dart Code
import 'package:http/http.dart';
import 'package:web3dart/web3dart.dart';

//import 'package:web3dart/transaction.dart'
const String privateKey =
    '12.......21.....12......21.........21';
const String rpcUrl = 'https://examplechain.org/v1/undefined';

Future<void> main() async {
  // start a client we can use to send transactions
  final client = Web3Client(rpcUrl, Client());

  final credentials = await client.credentialsFromPrivateKey(privateKey);
  final address = await credentials.extractAddress();

  print(address.hexEip55);
  print(await client.getBalance(address));
  Transaction transaction = Transaction(
    to: EthereumAddress.fromHex('0xFEED12......fdaE12'),
    gasPrice: EtherAmount.inWei(BigInt.one),
    maxGas: 100000,
    nonce: 0x101,
    value: EtherAmount.fromUnitAndValue(EtherUnit.ether, 101),
  );
  //await client.sendTransaction(credentials, transaction, chainId: 69696969);
  final signed =
      await client.signTransaction(credentials, transaction, chainId: 69696969);
  print(await client.sendRawTransaction(
    signed,
  ));

  /*await client.sendTransaction(
    credentials,
    Transaction(
      to: EthereumAddress.fromHex('0xBEACH123..........1F02'),
      gasPrice: EtherAmount.inWei(BigInt.one),
      maxGas: 100000,
      value: EtherAmount.fromUnitAndValue(EtherUnit.ether, 101),
    ),
    chainId: 108801,
    */
  // fetchChainIdFromNetworkId: true,

  await client.dispose();
}

Using the following code I can clearly able to transfer any amount to any target wallet address

//Web3js Code
const Web3 = require('web3');
const Tx = require('ethereumjs-tx').Transaction;
const Common = require('ethereumjs-common');
let web3 = new Web3("https://examplechain.org/v1/undefined");

const privKey =
Buffer.from('91919021.........................91d3767ed32112','hex'); // Genesis private key
const addressFrom = '0xFEED132ec........f8c5b6f8CfFFFF';
const addressTo = '0xFEED213...........2d8C449C';

web3.eth.getTransactionCount(addressFrom, (err, txCount) => {
    const txObject = {
        nonce: web3.utils.toHex(txCount),
        to: addressTo,
        value: web3.utils.toHex(web3.utils.toWei('400', 'ether')),
        gasLimit: web3.utils.toHex(100000),
        gasPrice: web3.utils.toHex(web3.utils.toWei('1', 'gwei'))
    };
    const common = Common.default.forCustomChain('mainnet', {
        name: 'newchain',
        networkId: 69696969,
        chainId: 69696969
      }, 'petersburg');
    const tx = new Tx(txObject,  {common});
    //const tx = new Tx(txObject,  {'chain':'56'});
    //const tx = new Tx(txObject,  {'chain':'binance'});
    tx.sign(privKey);

    const serializedTrans = tx.serialize();
    const raw = '0x' + serializedTrans.toString('hex');

    web3.eth.sendSignedTransaction(raw, (err, txHash) => {
        console.log('txHash:', txHash)
    });

I have the same problem

我也有同样的问题

After the transfer is successful, I can't find the transaction in the browser.

me to any solution, After the transfer is successful, I can't find the transaction?

[mostafahakak]

The transaction returns hash but doesn't appear on Etherscan or change the values. Please help :(

final sendFunction = contract.function('transfer');

await client.sendTransaction( credentials, Transaction.callContract ( from: ownAddress, contract: contract, function: sendFunction, parameters: [receiver, BigInt.from(10)], gasPrice: EtherAmount.inWei(BigInt.from(1000000)), maxGas: 100000,

  ),
    chainId: 4,
).then((value)  async{

  print("DONE");
  print(value);
  final balance = await client.call(
      contract: contract, function: balanceFunction, params: [ownAddress]);
  print('We have ${balance.first} EC');
});

in callContract: nonce: await provider.getTransactionCount(credentials!.address),

"gasPrice" in a network with eip1559 activated must not be included "from" is not needed if you send it from the same signer(credentials)
