推荐答案
有一种叫做 PureComponent 在本机反应中.如果您将 FlatList 项创建为 PureComponent，您会看到很多改进.在数据更改之前，它不会重新渲染项目.
There is something called PureComponent in react native. If you create your FlatList item as PureComponent, you can see lot of improvement. It will not rerender items untill data has been changed.
像这样:
class MyListItem extends React.PureComponent {
}
即使是 Nino9612 建议的库 react-native-optimized-flatlist 也使用相同的概念，你可以看到他们的代码 FlatListItem
Even the library suggested by Nino9612 react-native-optimized-flatlist is also using the same concept, as you can see code of their FlatListItem
