This may lead to a less comprehensive review. Walkthrough对 Collapse 组件的内部状态管理进行了重构：由 useMergedState 切换为 useControlledState 与 useEvent 的受控/非受控模式；统一通过 getActiveKeysArray 派生 activeKey，并使用 triggerActiveKey 进行状态更新与 onChange 调用。并将 @rc-component/util 依赖从 ^1.0.1 升级到 ^1.3.0。 Changes

Summary of Changes
Hello @EmilyyyLiu, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
此 PR 主要进行了一项重构，旨在更新项目所依赖的工具库版本，并替换组件内部的状态管理 Hook。通过升级 @rc-component/util 并迁移到 useControlledState，提高了组件对受控和非受控状态处理的灵活性和一致性，同时优化了事件触发机制。
Highlights
- 依赖升级: 将
package.json中的@rc-component/util版本从^1.0.1升级到^1.3.0。 - 替换状态管理 Hook: 在
src/Collapse.tsx中，将useMergedState替换为useControlledState和useEvent。 - 重构
activeKey逻辑: 调整Collapse组件中activeKey的状态管理逻辑，以适应useControlledState的使用，并优化onItemClick的触发方式。

在 triggerActiveKey 函数中，使用 next !== activeKey 来判断数组是否发生变化是不正确的。因为 next 和 activeKey 总是不同的数组实例，即使它们的内容完全相同，这个条件也始终为 true。这会导致 onChange 回调在每次点击时都会被不必要地触发，可能引起父组件的额外渲染。之前的 useMergedState 内部使用了浅比较来避免此问题，建议此处也实现一个浅比较逻辑。
if (
next.length !== activeKey.length ||
next.some((key, index) => key !== activeKey[index])
) {
onChange?.(next);
}

当前的 onItemClick 函数逻辑虽然是正确的，但代码结构有些迂回，可读性不强。代码首先假定添加 key，然后根据 accordion 模式和 isActive 状态覆盖这个值。为了提高代码的可读性和可维护性，建议重构此函数，使用更明确的 if/else 结构来处理不同情况。
const onItemClick = (key: React.Key) => {
let newKeys: React.Key[];
if (accordion) {
newKeys = activeKey[0] === key ? [] : [key];
} else {
const index = activeKey.indexOf(key);
const isActive = index > -1;
if (isActive) {
newKeys = activeKey.filter((item) => item !== key);
} else {
newKeys = [...activeKey, key];
}
}
triggerActiveKey(newKeys);
};

10-18: 建议优化类型安全性
getActiveKeysArray函数实现正确，但可以通过更严格的类型检查来提高代码质量。function getActiveKeysArray(activeKey: React.Key | React.Key[]): React.Key[] { let currentActiveKey = activeKey; if (!Array.isArray(currentActiveKey)) { - const activeKeyType = typeof currentActiveKey; - currentActiveKey = - activeKeyType === 'number' || activeKeyType === 'string' ? [currentActiveKey] : []; + currentActiveKey = + currentActiveKey !== undefined && currentActiveKey !== null ? [currentActiveKey] : []; } return currentActiveKey.map((key) => String(key)); }这种方式可以更好地处理
null和undefined值，同时简化逻辑。
54-65: 建议简化 onItemClick 逻辑当前实现功能正确，但可以通过提前返回来简化逻辑流程。
const onItemClick = (key: React.Key) => { - let keys = [...activeKey, key]; if (accordion) { - keys = activeKey[0] === key ? [] : [key]; + const keys = activeKey[0] === key ? [] : [key]; + triggerActiveKey(keys); + return; } + const index = activeKey.indexOf(key); const isActive = index > -1; - if (isActive) { - keys = activeKey.filter((item) => item !== key); - } + const keys = isActive + ? activeKey.filter((item) => item !== key) + : [...activeKey, key]; triggerActiveKey(keys); };这种方式使手风琴模式和多选模式的逻辑更加清晰分离。

50-50: 依赖版本升级看起来不错！将
@rc-component/util从^1.0.1升级到^1.3.0以支持新的useControlledState和useEventhooks 是合理的。这个版本升级幅度适中，应该不会引入破坏性变更。src/Collapse.tsx (2)
2-2: 成功迁移到新的状态管理模式从
useMergedState迁移到useControlledState和useEvent的组合是一个很好的重构，使代码更加清晰和符合现代 React 模式。
41-45: 状态管理实现正确使用
useControlledState处理受控/非受控模式，并通过getActiveKeysArray派生activeKey的实现很清晰。这种模式能够正确处理各种输入类型。
