Is there a way to prevent the color from changing? I currently have a random color generator in place, but I want to store that color in a state. Any suggestions on how I can achieve this

I'm working on creating a team bracket generator using react native, but I've encountered an issue. Every time I add a new object to the array, the color updates. I understand that the render function is updating with each action, but I'm wondering how I can prevent this from happening?

Answer №1

It's recommended to utilize state to store the background color and then pass that state to the style in AddName component

Step One:

const [customColor, setCustomColor] = useState(`#${Math.floor(Math.random() * 16777215).toString(16)}`)

Step Two

Implement it as shown below

<SafeAreaView style={{...gstyles.RectangleShapView, ...gstyles.aligningAndJystify, backgroundColor: customColor}}>
