我试图找出尽可能多的方法来优化 flatlist，因为我的 flatlist 组件抱怨我的 flatlist 项目需要太长时间来呈现（我已经在使用 removeClippedSubviews、windowSize、maxToRenderPerBatch、React.memo 等）。

用 useCallback 包装渲染函数是个好主意吗？

例如，假设我最初具有表单中的函数组件：

const FlatListItem = ({ color1, color2, color3, color4 }) => {
  function renderViewWithColorLogic(color) {
    // do some computationally heavy process
    // ...

    return <View>{/* some components */}</View>;
  }

  return (
    <View>
      {renderViewWithColorLogic(color1)}
      {renderViewWithColorLogic(color2)}
      {renderViewWithColorLogic(color3)}
      {renderViewWithColorLogic(color4)}
    </View>
  );
};

如果我使用 useCallback 将渲染函数包装为：

const FlatListItem = ({ color1, color2, color3, color4 }) => {
  function _renderViewWithColorLogic(color) {
    // do some computationally heavy process
    // ...

    return <View>{/* some components */}</View>;
  }
  const renderViewWithColorLogic1 = useCallback(()=>_renderViewWithColorLogic(color1), [color1])
  const renderViewWithColorLogic2 = useCallback(()=>_renderViewWithColorLogic(color2), [color2])
  const renderViewWithColorLogic3 = useCallback(()=>_renderViewWithColorLogic(color3), [color3])
  const renderViewWithColorLogic4 = useCallback(()=>_renderViewWithColorLogic(color4), [color4])

  return (
    <View>
      {renderViewWithColorLogic1()}
      {renderViewWithColorLogic2()}
      {renderViewWithColorLogic3()}
      {renderViewWithColorLogic4()}
    </View>
  );
};

它会增强 flatlist 的性能吗？任何其他优化 flatlist 的建议也将不胜感激。

就安德烈斯所说，我认为通过一些计算实现平面列表项组件的更好方法如下：

const FlatListItem = ({ color1, color2, color3, color4 }) => (
  const viewWithColorLogic1 = useMemo(()=>_renderViewWithColorLogic(color1), [color1]);
  const viewWithColorLogic2 = useMemo(()=>_renderViewWithColorLogic(color2), [color2]);
  const viewWithColorLogic3 = useMemo(()=>_renderViewWithColorLogic(color3), [color3]);
  const viewWithColorLogic4 = useMemo(()=>_renderViewWithColorLogic(color4), [color4]);

  return (
    <View>
      {viewWithColorLogic1}
      {viewWithColorLogic2}
      {viewWithColorLogic3}
      {viewWithColorLogic4}
    </View>
  );
);

function renderViewWithColorLogic(color) {
    // do some computationally heavy process
    // ...

    return <View>{/* some components */}</View>;
}
