computeProjectId() → Future<String>: A convenience wrapper that first tries projectIdFromEnvironment then (if the value is null) tries projectIdFromMetadataServer
createLoggingMiddleware({String? projectId}) → Middleware: Convenience Middleware that handles logging depending on projectId.
listenPort() → int: Returns the port to listen on from environment variable or uses the default 8080.
projectIdFromEnvironment() → String?: Returns the Project ID for the current Google Cloud Project by checking the environment variables in gcpProjectIdEnvironmentVariables.
projectIdFromMetadataServer() → Future<String>: Returns a Future that completes with the Project ID for the current Google Cloud Project by checking project metadata.
serveHandler(Handler handler) → Future<void>: Serves handler on InternetAddress.anyIPv4 using the port returned by listenPort.
waitForTerminate() → Future<void>: Returns a Future that completes when the process receives a ProcessSignal requesting a shutdown.

BadConfigurationException: Thrown if a service is configured incorrectly.
BadRequestException: When thrown in a Handler, configured with badRequestMiddleware or similar, causes a response with statusCode to be returned.
