Add const in front of handleClick on line 44.

const handleClick = (e) => {
  //
}

I'm now getting the error undefined is not an object (evaluating 'e.target.name'), just to clarify I'm copying this code from a solution I saw on stack overflow: https://stackoverflow.com/questions/54665021/how-to-change-color-of-button-on-press-in-react-native – shange Oct 23 '22 at 11:50

I think it is better for you to pass your variable instead of using default event value in handleClick().

onPress={()=>{
  this.handleClick("YOUR_VALUE");
}}

And you can create your own handleClick() like this.

handleClick = (data) =>{
  console.log(data); // <- should output "YOUR_VALUE"
}
