描述

  • I have searched the issues of this repository and believe that this is not a duplicate.

Reproduction link

Edit on CodeSandbox

Steps to reproduce

  1. consume Grid.useBreakpoint();
  2. initial render will display empty object

What is expected?

I would expect Grid.useBreakpoint() to return an initial value on the first render. This could also potentially not rerender a component consuming Grid.useBreakpoints().

You could initiate it by checking window.innerWidth on mount.

I would be happy to create a PR for this.

What is actually happening?

initial render of Grid.useBreakpoint() displays an empty object

研究方向
Look into the implementation of `Grid.useBreakpoint` in the ant design source code, likely in `components/grid/hooks/useBreakpoint.ts` or similar. The issue suggests initializing with `window.innerWidth` on mount. Check existing responsive hooks for patterns. Review the comments in the issue for any maintainer guidance.
