React Native Redux，如何设置导航道具？

Question

如何设置导航选项？ 我应该在哪里做？通常我会在Redux Saga中改变这些效果：

export function* validateLogin(action) {
    if (action.payload.email === '' || action.payload.password === '') 
        yield put(onLoginFailed)
    else {
        yield call(Keychain.setGenericPassword, 'token', 
        action.payload.password)
        yield put(onLoginSuccess)
        yield put(NavigationActions.navigate({ routeName: 'App' }))
    }   
}
