# ServiceExtensionResponse.result constructor Null safety

ServiceExtensionResponse.result(

1. String result

)

Creates a successful response to a service protocol extension RPC.

Requires `result` to be a JSON object encoded as a string. When forming the JSON-RPC message `result` will be inlined directly.

## Implementation

    ServiceExtensionResponse.result(String result)
        : result = result,
          errorCode = null,
          errorDetail = null {
      // TODO: When NNBD is complete, delete the following line.
      ArgumentError.checkNotNull(result, "result");
    }
