Walkthrough

此次更改提升了多个组件的健壮性和可读性，主要通过引入更安全的空值检查和简化的代码逻辑。对于Sticky组件，使用了可选链操作符来处理潜在的未定义引用，简化了样式计算和滚动处理逻辑。getScrollParent函数的参数类型也进行了调整，以支持null和undefined，进一步增强了其容错能力。

Changes

文件	变更摘要
src/packages/sticky/sticky.taro.tsx src/packages/sticky/sticky.tsx	主要是代码重构，提高了可读性和健壮性，特别是在空值检查和样式计算方面进行了优化。handleScroll函数和useEffect钩子的逻辑也被简化，以减少潜在的运行时错误。
src/utils/get-scroll-parent.ts	getScrollParent函数的el参数类型更改为`Element

Chat

There are 3 ways to chat with CodeRabbit:

‼️ IMPORTANT
Auto-reply has been disabled for this repository in the CodeRabbit settings. The CodeRabbit bot will not respond to your replies unless it is explicitly tagged.

• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  • @coderabbitai generate unit testing code for this file.
  • @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  • @coderabbitai generate interesting stats about this repository and render them as a table.
  • @coderabbitai show all the console.log statements in this repository.
  • @coderabbitai read src/utils.ts and generate unit testing code.
  • @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  • @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
