React Native Router Flux 道具不通过动作

React Native Router Flux props not passing through action

我正在尝试从我的按钮传递一些数据

   <Button
                text="Explore"
                elementStyles={secondaryButton}
                onPress={() => Actions.dashboard({
                  demoMode: true,
                })}
                testID="button-explore"
              />

位于Example.js,至Dashboard.js

这是我的路由器堆栈,位于 App.js

<Stack key="root" hideNavBar>
              <Scene key="splash" initial component={SplashScreen} />
              ....
              <Scene key="example" component={example} />
              ....

              <Tabs key="tabbar" hideNavBar tabBarPosition="bottom" showLabel={false} tabBarStyle={styles.tabBar} swipeEnabled={false} animationEnabled={false}>
                <Scene key="dashboard" hideNavBar title="Dashboard" component={Dashboard} icon={TabBarItem} defaultIcon={Config.HOME_ICON_NAME} />
                <Scene key="history" hideNavBar title="Stats" component={History} icon={TabBarItem} defaultIcon={Config.STATS_ICON_NAME} />
                <Scene key="rewards" hideNavBar title="Points" component={Rewards} icon={TabBarItem} defaultIcon={Config.REWARDS_ICON_NAME} />
                <Scene key="profile" hideNavBar title="Profile" component={Profile} icon={TabBarItem} defaultIcon={Config.PROFILE_ICON_NAME} />
              </Tabs>
 />

            </Stack>

当我在仪表板下调用 this.props.demoMode 时,我得到了未定义的信息。

您好,请尝试在第二个屏幕键之前添加 _

onPress={() => Actions._dashboard({
              demoMode: true,
            })}

类似的东西,但如果它不起作用,请删除您的节点模块文件夹,更改路由器通量版本,再次 npm i,您会没事的
