Red error box keeps appearing even though the Error boundary capturing the error.
<ErrorBoundary fallback ={()=> }>
Is this a bug or will this happen in production. Is there any way to turn this off?. I’m still new to mobile developing
It sounds like you’re encountering an error message that persists even when you’re using an ErrorBoundary. This can be a bit tricky, but let’s break it down.
What’s Happening
Error Boundary: The ErrorBoundary component is designed to catch JavaScript errors in its child component tree. If it’s working correctly, it should prevent the red error box from appearing.
Fallback Component: The fallback prop is where you can specify what to render when an error is caught. If your fallback is not rendering anything (e.g., () => {}), you may still see the default error overlay.
Possible Reasons for the Error Box
Improper Setup: Ensure that your ErrorBoundary is correctly set up to wrap the components that may throw errors.
Multiple Errors: If there are multiple components that are throwing errors, ensure that the ErrorBoundary is high enough in the tree to catch all of them.
React Native Specifics: If you are using React Native, be aware that it can sometimes show errors in a different way compared to React for web.
How to Handle It
Update Fallback: Make sure your fallback function renders something meaningful, even if it’s just a simple message:
jsx
<ErrorBoundary fallback={<Text>Something went wrong!</Text>}>
Check for Other Errors: Look through your code and the console for other potential issues that might not be caught by the ErrorBoundary.
Disable Debugging Mode: If you are in development mode, the error box might show more frequently. In production, React Native typically hides these overlays unless specified otherwise.
Using Try-Catch: For areas where you anticipate errors, consider wrapping those parts in a try-catch block to handle them more gracefully.
In Production
In production, the error boundary should work as intended, and you shouldn’t see the red error box if it’s properly catching errors. However, it’s crucial to test thoroughly before deploying.
