getAutoSwitchBestConnection method

Future<bool?> getAutoSwitchBestConnection(bool autoSwitch)

Gets the auto-switch connection setting for the Haveno daemon.

This method queries the Haveno daemon to check whether the automatic switching to the best available Monero (XMR) connection is enabled or disabled.

If the Haveno channel is not connected, a DaemonNotConnectedException will be thrown.

It returns a bool indicating the current auto-switch setting:

• true if auto-switch is enabled.
• false if auto-switch is disabled.

If there is a communication error (e.g., a gRPC error), the error will be caught and handled using the handleGrpcError method.

Parameters:

• autoSwitch: A boolean flag that specifies the setting to check for the auto-switch mechanism (not actively used in this method but could be passed).

Returns:

• A Future that resolves to a bool indicating the auto-switch state:
  • true: Auto-switch is enabled.
  • false: Auto-switch is disabled.
  • null: If an error occurs or if no response is received.

Throws:

• DaemonNotConnectedException if the Haveno daemon is not connected.

Example usage:

bool? autoSwitchStatus = await getAutoSwitchBestConnection();
if (autoSwitchStatus != null && autoSwitchStatus) {
  print("Auto-switch to best XMR connection is enabled.");
} else {
  print("Auto-switch to best XMR connection is disabled.");
}

Implementation

Future<bool?> getAutoSwitchBestConnection(bool autoSwitch) async {
  // Check if the Haveno daemon is connected.
  if (!havenoChannel.isConnected) {
    throw DaemonNotConnectedException(); // Throw exception if not connected.
  }

  try {
    // Send request to get the current auto-switch setting from the XMR connections client.
    GetAutoSwitchReply getAutoSwitchReply = await havenoChannel.xmrConnectionsClient!
        .getAutoSwitch(GetAutoSwitchRequest());

    // Return the current auto-switch setting.
    return getAutoSwitchReply.autoSwitch;
  } on GrpcError catch (e) {
    // Handle any gRPC-related errors.
    handleGrpcError(e);
  }

  // Return null if an error occurs or no valid response is received.
  return null;
