Solving the undefined is not an object Error in React Native

Understanding the Problem

You are trying to update the current balance displayed on the Home screen whenever a user adds balance through the Add Balance component. However, you're encountering an error because the props being passed to the Home component may not be correctly structured. The specific error message indicates that the application is looking for the money property, but it can't find it, which leads to an undefined object.

Here’s an overview of the scenario:

You have a Home component that is attempting to display the current balance.

You have an AddBalance component where users can input an amount to add to their balance.

The connection between these two components is where the problem lies, leading to the error message being displayed.

The Solution

To solve the undefined is not an object error and successfully pass the balance state between components, follow these structured steps:

Step 1: Update the Home Component

Change the way you define the parameters in the Home component. Instead of using { props, navigation }, simplify it by just using props. Here's how to do it:

Step 2: Ensure Navigation is Correctly Passed
