WalletConnect V2 Flutter documentation not available

[Aastha9018]

Hey, I have tried really hard but there's no proper documentation for the flutter app integration with wallet Connect v2. Can you please help me with some of the links.
Also the documentation present on the official website is just screenshots of snippets which aren't really healpful and then when i try tp google some bugs that I'm facing, there's no material for that as well. Please help me.

LAstly can you help me to any documentation maybe flutter/react-native or any other where the event handling is metioned for wallet_addEthereumChain.

Hi,

I am using the example app in the Flutter.
I am running the wallet app in my local system.
I tried connecting it to Remix. The default chain that it gets connected to is Arbitrum(42161). After trying to switch it to Georli, now I'm trying to deploy a contract in Remix but it gives me the error. The first time it says that Invalid/Missing parameters and the second time that the eth_sendTransaction method doesn't exist. You can see the screenshots.

In the Web3Client, I have changed the URL from https://mainnet.infura.io/v3/51716d2096df4e73bec298680a51f0c5 to https://goerli.infura.io/v3/, still it fails.
I googled the error, and it states that using Infura RPC URLs maybe give the error, so I changed it to https://rpc-mumbai.maticvigil.com/v1/83ca0e94a4324ee57e324ceb6cb1a41b2420cbda still the same issue.
Whereas if I try connecting to the WalletConnect official app, it succeeds: https://react-app.walletconnect.com/

Can you please help me resolve it?
Much appreciated, thanks.
