Implementation

  final bridge = params['bridge'] ??
      (throw WalletConnectException('Missing bridge param in URI'));

  final key = params['key'] ??
      (throw WalletConnectException('Missing key param in URI'));

  return WalletConnectSession(
    protocol: protocol,
    version: int.tryParse(version) ?? 1,
    handshakeTopic: handshakeTopic,
    bridge: Uri.decodeFull(bridge),
    key: Uint8List.fromList(hex.decode(key)),
