How can I get unique data-id in event so that respective state can be updated using that id?

I want to specify a unique id to each SketchPicker so that I can setState on basis of id.
But I'm unable to get this id in the event!

```
handleTxtColorChange = (color: any, event: any): void => {
console.log(event);
this.setState({ metricTextColor: color.hex });
}

{this.state.conditions.map((condition, key) => (

)}
```
