Describe the bug I have connected Tron network on TrustWallet but can't sign transaction, I am getting error

sonRpcError(code: 5201, message: Unknown method(s) requested)

is there any example available in flutter except EVM chains? I tested the web example of dapp from WalletConnect V2 and I was able to see sign transaction in TrustWallet but doesn't work in Flutter, am I doing something wrong or anything missing ? if anyone have done sign transaction on tron chain Please share example

method : tron_signTransaction chain : tron:0x2b6653dc params :{from: TD7Ve4TigHpR4PzP6K5LFCyKsYBFRbApov, to: TQUiQy5Mdrdps8tTqj35WNHkVJCYjCsfvX, value: 0x16e364}

when connecting I have provided tron_signTransaction method

 optionalNamespaces: {
          'eip155': RequiredNamespace(
            chains: Web3Helper.getChains(wallet.web3Wallet),
            methods: Web3Helper.rpcOptionalMethods,
            events: Web3Helper.rpcEvents,
          ),
          'tron': RequiredNamespace(
            chains: [
              "tron:0x2b6653dc",
            ],
            methods: ['tron_signTransaction', 'tron_signMessage'],
            events: [],
          ),
        },

Hello @AmjadKhan2k18! Flutter SDK currently supports only EVM chains. We are working towards non-EVM chains but it might take some time.
