# ServiceExtensionResponse.result constructor

ServiceExtensionResponse.result(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 {
      if (_result is! String) {
        throw new ArgumentError.value(_result, "result", "Must be a String");
      }
    }
