How can I handle errors in React Native using Context API?

You can handle errors in React Native using the Context API by creating a context for error management. This involves defining an error state and a function to update that state.

Can you show me a code example of how to implement this?

Sure! First, create an ErrorContext with a provider. Then, use a state variable to hold the error message and a function to set it. Here's a simple example:

const ErrorContext = React.createContext();

const ErrorProvider = ({ children }) => {
    const [error, setError] = useState(null);

    return (
        <ErrorContext.Provider value={{ error, setError }}>
            {children}
        </ErrorContext.Provider>
    );
};

You can then use this context in your components to display errors.

What about catching errors in async functions?

For async functions, you can use try-catch blocks. Inside the catch block, you can call the setError function from your context to update the error state.

Thanks! How do I reset the error state after handling it?

You can reset the error state by calling setError(null) after you've displayed the error message or handled it appropriately.
