  1. Create instance of Wallet connect client and define callbacks.

    final wcClient = WCClient(
      onConnect: () {
        // Respond to connect callback
      },
      onDisconnect: (code, reason) {
        // Respond to disconnect callback
      },
      onFailure: (error) {
        // Respond to connection failure callback
      },
      onSessionRequest: (id, peerMeta) {
        // Respond to connection request callback
      },
      onEthSign: (id, message) {
        // Respond to personal_sign or eth_sign or eth_signTypedData request callback
      },
      onEthSendTransaction: (id, tx) {
        // Respond to eth_sendTransaction request callback
      },
      onEthSignTransaction: (id, tx) {
        // Respond to eth_signTransaction request callback
      },
    );
  1. Create WCSession object from wc: uri.

    final session = WCSession.from(wcUri);
  1. Create WCPeerMeta object containing metadata for your app.

    final peerMeta = WCPeerMeta(
        name: 'Example Wallet',
        url: 'https://example.wallet',
        description: 'Example Wallet',
        icons: [],
    );

    wcClient.connectNewSession(session: session, peerMeta: peerMeta);
  1. Or connect to a saved session (from step 8).

    wcClient.connectFromSessionStore(sessionStore);

    wcClient.approveSession(
        accounts: [], // account addresses
        chainId: 1, // chain id
    );

    wcClient.rejectSession();
  1. Get active session from sessionStore getter to save for later use.

    final sessionStore = wcClient.sessionStore;

    wcClient.approveRequest<String>(
        id: id,
        result: signedDataAsHex,
    );
  1. Approve a send transaction request by sending the transaction hash generated from sending the transaction.

    wcClient.approveRequest<String>(
        id: id,
        result: transactionHash,
    );
  1. Approve a sign request by sending the signed data hex generated.

    wcClient.approveRequest<String>(
        id: id,
        result: signedDataAsHex,
    );
  1. Or reject any of the requests above by specifying request id.
