Walletconnect does not stay connected

Question

I am using walletconnect_dart to connect my app to Metamask. Scanning the QR code or mobile deep link all works well and is immediately connected to the wallet.

The issue I am facing is that when I restart the app, my wallet is no longer connected to the app. Every time I have to reconnect my wallet to the application with a deep link/QR code.

Is there any way to stay connected to the wallet even after restarting the app?

This is how I am connecting to the wallet

               final connector = WalletConnect(
                      bridge: 'https://bridge.walletconnect.org',
                      clientMeta: const PeerMeta(
                        name: 'WalletConnect',
                        description: 'WalletConnect Developer App',
                        url: 'https://walletconnect.org',
                        icons: [
                          'https://gblobscdn.gitbook.com/spaces%2F-LJJeCjcLrr53DcT1Ml7%2Favatar.png?alt=media'
                        ],
                      ),
                    );

                    // Subscribe to events
                    connector.on('connect', (session) => print(session));
                    connector.on('session_update', (payload) => print(payload));
                    connector.on('disconnect', (session) => print(session));

                   // Create a new session
                    if (!connector.connected) {
                      final session = await connector.createSession(
                        chainId: 4160,
                        onDisplayUri: (uri) {
                          launchUrl(Uri.parse(uri));
                        },
                      );

                      print(session);
                    }

Hello @hemal, Were you able to integrate walletConnect properly in flutter? — Vivek Makwana, Jul 04 '22 at 10:26
I have tried the same way as your block of the code, But once the URI is launch in metamask, I don't get connect to wallet option — Vivek Makwana, Jul 05 '22 at 04:30

I used walletconnect_secure_storage package to overcome this issue.

first, initialize the wallet connect storage

 WalletConnectSecureStorage sessionStorage = WalletConnectSecureStorage();

After that, when you successfully connected with wallet connect (For that I have used walletconnect_dart), you will get WalletConnectSession from the instance of wallet connect

And store WalletConnectSession to sessionStorage as mentioned below

sessionStorage.store(walletConnect.session)

After doing this, Your session is successfully stored in sessionStorage

Now in initState we will get our session from sessionStorage and assign it to walletConnect instance as mentioned below

  final session = await UserDataUtils.sessionStorage.getSession();

    // Create a connector
    walletConnect = WalletConnect(
      bridge: 'https://bridge.walletconnect.org',
      session: session,
      sessionStorage: sessionStorage,
      clientMeta: const PeerMeta(
      name: 'WalletConnect',
      description: 'WalletConnect Developer App',
      url: 'https://walletconnect.org',
      icons: [
      'https://gblobscdn.gitbook.com/spaces%2F-LJJeCjcLrr53DcT1Ml7%2Favatar.png?alt=media'
    ],
  ),
);

You can also register listeners

walletConnect.registerListeners(onConnect: (status) {
      print(status);
    }, onDisconnect: () {
      print('Disconnect');
    });

I have same code in my project but when I close trustwallet & my app for few minutes, once i am back and try to make transaction using _connector.sendCustomRequest it doesn't show confirmation popup in trustwallet for metamask it's working fine but TrustWallet session doesn't work — Amjad Khan, Feb 08 '23 at 15:15
