Hello,

I'm creating a new visualization type, but when I add it to the dashboard , the toast shows "undefined" added. How can I set an initial value for this component to show it in the Toast?

Thanks!

You can read up on some information about building plugins here [https://www.elastic.co/guide/en/kibana/current/development-plugin-resources.html](https://www.elastic.co/guide/en/kibana/current/development-plugin-resources.html)

I'd suggest grabbing the source from [https://github.com/elastic/kibana](https://github.com/elastic/kibana), try making your edits in the source, and then run Kibana in dev mode with `npm start` . You'll get source maps that will make debugging the issue easier using your browser's dev tools.

Hello @rashmi I received some feedback in Slack. The change didnt fix the issue but it is a step in the right direction, and it is changing the initialInput property in the component constructor, setting the "title" property.
