I am trying to connect my flutter mobile application with the metamask mobile application using web3modal_flutter and walletconnect. Basically, I am trying to interact with the smart contract and also want to pass the arguments for the functions that are required. Connecting on Sepolia test network. using: web3modal_flutter: ^3.1.1-beta02 walletconnect_flutter_v2: ^2.1.11 this is my code for the file:

Please follow documentation (there's a handy video at the bottom) and get back it you still have issues. https://docs.walletconnect.com/web3modal/flutter/installation

Hi, thank you for your reply. I have written the connection logic in a separate file. Below I have given the code of both my files. The application runs and Metamask is opened whenever the connect button is pressed. However, whenever a writeContract or readContract transaction is initiated, Metamask opens up as expected, but the transaction confirmation pop-up is not being displayed.

Code for connection logic file:

Hello @sethitanay ! Thanks for the detailed response. Btw, if you use dependency_overrides

dependency_overrides:
   walletconnect_flutter_v2: 2.2.2

You don't need to add the same dependency in main dependencies This is what you need:

dependencies:
   web3modal_flutter: ^3.1.2

dependency_overrides:
   walletconnect_flutter_v2: 2.2.2

That being said, do you see the same issues with other wallets? I can't not help to much without the ABI file and the contract address but I see Error calling write function: Null check operator used on a null value so I would say you are missing the from value in your Transaction. Can you try this?

await _w3mService.requestWriteContract(
  topic: _w3mService.session!.topic.toString(),
  chainId: 'eip155:11155111',
  rpcUrl:
      'https://eth-sepolia.g.alchemy.com/v2/Is7xCCuFmVXsJ1RvScVGEiCMggxETN7U',
  deployedContract: deployedContract,
  functionName: 'authorizeVoter',
  parameters: [
    addressController.text,
    nameController.text,
    ageController.text,
    genderController.text
  ],
  transaction: Transaction(
    from: EthereumAddress.fromHex(_w3mService.session!.address!),
  ),
);

I did the changes as suggested by you but still my problem is not solved.

Hello @sethitanay! A few things....

  1. You need to await the init() method of _w3mService, and since this can not be don in initState() because, like I said before, that function shouldn't be async, you should find a better way of initializing W3MService(), check the sample app.
  2. You are initializing _w3mService TWICE. On your MetamaskConnector and AuthorizeVoterScreen, why? You shouldn't do that.
  3. If you use includedWalletIds you don't need to use excludedWalletIds
  4. You are passing the wrong parameters to the contract function. Like I said, Transaction object should have the from value (and you have added it) but the parameters you are passing are not of the type requested by the contract function. You are passing ALL STRINGS while your contract function is defined as follows (type address, type string, type uint256, type string):
{
  "inputs": [
    {
      "internalType": "address",
      "name": "_voterAddress",
      "type": "address"
    },
    {
      "internalType": "string",
      "name": "_name",
      "type": "string"
    },
    {
      "internalType": "uint256",
      "name": "_age",
      "type": "uint256"
    },
    {
      "internalType": "string",
      "name": "_gender",
      "type": "string"
    }
  ],
  "name": "authorizeVoter",
  "outputs": [],
  "stateMutability": "nonpayable",
  "type": "function"
},

therefor this is completely wrong:

parameters: [
            addressController.text,
            nameController.text,
            ageController.text,
            genderController.text
          ],

Here it is a complete working example of your code (tested it with Zerion Wallet):
