Update theme_object.mdx

[HadiaRafiq]

Motivation

The spacing object was added to the theme to provide a standardized and scalable way to manage layout spacing (such as padding, margin, and gaps) across the app. Hardcoding pixel values often leads to inconsistent UI and makes global updates difficult. By centralizing spacing in the theme, we enable consistent styling, easier maintenance, and better alignment with design systems.

Additional context

Hello @HadiaRafiq - thank you for the PR! I am a new contributor and am working to review and merge your PR. I found a few issues that need to be addressed:

1. Syntax Error

interface Spacing: { // ❌ Remove the colon

Should be:

interface Spacing {

2. Incorrect Default Values

The examples don't match the actual defaults in the codebase. According to packages/base/src/helpers/index.tsx, the defaults are:
{ xs: 2, sm: 4, md: 8, lg: 12, xl: 24 }
Not
{ xs: 4, sm: 8, md: 16, lg: 24, xl: 32 }

3. Interface Naming

For consistency with the source code and the Colors section pattern, consider using ThemeSpacing instead of Spacing since that's the actual type name exported from @rneui/base/dist/helpers.

Could you update the PR to fix the syntax error and use the correct default values & naming?

EDIT: Made changes myself, will merge
