WalletConnect
having an error when signing a safe multisig wallet transaction connected with flutter
i am trying to connect flutter with safe multisig wallet in app.safe.global/sepolia and
i tried to connect it with the documentation like this code snippet below and everything other than safe works like metamask but safe says the image i posted below and my code snippet is also attached help
my code snippet is

Hello @ezrablackfish2, I'll take a look as soon as I can, in the meantime, are you sure this is the complete code? Seems to be missing a part at the beginning.
Also, do you mind checking other wallets? Just to see if could be an issue on Safe side.
thank you so much for taking the time this simply is my plan i want to connect flutter with safe wallet and be able to call a smart contract that was a simple plan if there are other ways i be happy to do that
