What exactly is the issue?

"I need help creating (deploying?) contracts and documentation for deployed contracts" doesn't give me the info I need to help you.

It looks like you are trying to execute a custom contract call. I assume it isn't working. What's the error that you're getting?

        Future<dynamic> future =   testContractStore2(walletConnect: widget.web3App, session: widget.session, contractAddress: '0xaaE9BcA71Eb2B03E36E9579C1C263042869d84A9', value: 0.00007355491950105679);

Future testContractStore2({ required Web3App walletConnect, required SessionData session, required String contractAddress,

required double value, }) async { // Getting the deployed contract using ABI and contract address debugPrint("12"); final contract = DeployedContract( ContractAbi.fromJson( await rootBundle.loadString('assets/abis/tokenAbi.abi.json'), 'TestStorage1', // The name of the contract ), EthereumAddress.fromHex(contractAddress), ); // Create a transaction from contract, mint function and data uri. BigInt amountInWei = BigInt.from(0.000001 * 1000000000000000000);

final Transaction transaction = Transaction.callContract( contract: contract, // The contract to call the function on function: contract.function('transfer'), // The function to call parameters: [ EthereumAddress.fromHex(contractAddress),

  amountInWei
   ],

); // Send the transaction to the wallet to be executed return await walletConnect.request( topic: session.topic, chainId: NamespaceUtils.getChainFromAccount( session.namespaces.values.first.accounts.first, ), request: SessionRequestParams( method: 'eth_sendTransaction', params: transaction.toJson( // From address is the account of the session fromAddress: NamespaceUtils.getAccount( session.namespaces.values.first.accounts.first, ), toAddress: "0x710dcda140962b487e6934e7fa8fa6be62a5c61e", ), ), );

I have created a custom contract call here: https://github.com/WalletConnect/Web3ModalFlutter/blob/2981053456ecd3511ca2e3a7f0def7c75e22af62/example/sign/lib/utils/crypto/eip155.dart#L197

Looks like you need to put your transaction json into an array to get it to work.
