This can be particularly tricky since IconTint uses a <canvas> element under the hood, and simply rerendering the component often doesn’t yield the expected results. In this guide, we’ll explore the problem and provide a structured solution that allows you to achieve the desired effect seamlessly. Understanding the Problem The challenge arises because <IconTint /> is a memoized component. This means that it won’t rerender unless its props explicitly change, which can complicate our ability to change colors in response to state changes. Initial Attempts Many developers might try to change the color using a conditional rendering approach, like this: [[See Video to Reveal this Text or Code Snippet]] However, this approach does not work because even though they seem like two different components, they reference the same props that the memoized component checks. The Solution To efficiently change the color of the <IconTint /> element based on state, we can optimize our approach by modifying how we leverage React's useEffect and props. Here’s how you can implement this: Step 1: Create a Custom IconTint Component We can start by building a modified version of the IconTint component that ensures it rerenders upon prop changes. [[See Video to Reveal this Text or Code Snippet]] Step 2: Using the Modified Component Now that we have a custom IconTint component that respects color changes, we can use it in our application: [[See Video to Reveal this Text or Code Snippet]] This setup will ensure that the color updates dynamically based on the value of isActive. Conclusion By modifying the IconTint component and managing prop changes effectively, you can successfully change the color dynamically in your React application. This method not only provides a solution to the immediate problem but also ensures better performance and maintainability in your projects. Happy coding!
