React navigation v5 在屏幕上获取 initialParams 道具

Question

我已经尝试过很多次initialParams了this.props.navigation.state.params。这没有帮助。请帮助我如何获得这些参数。

<Stack.Screen name="FromMainScreenToSubCats" component={FromMainScreenToSubCats} initialParams={{catId:1 , title:'Filmler'}} />

Answer 1

您可以访问参数 this.props.route.params
