QUESTION
The WebView Code
...ANSWER
Answered 2021-May-30 at 13:47The problem is that the Webview
(ModalView
) assigns its own parent. This is a feature of the ModalView
. By returning a Webview
instance in your build()
method, you are attempting to set the App
as the parent of the Webview
. That causes the error you are seeing. You can solve this by returning something other than a Webview

QUESTION
I am using react-redux for my react project, apparently, there are 2 ways to use the redux state
connect
or useSelector
,
My redux store has a reducer for each page,
For Home Page > homePageReducer
For Message Page > messagePageReducer
For Authentication > authReducer
For User's blog > blogReducer
For Settings > userSettingsReducer
For User's Profile > userProfileReducer
In my top-level component or the main component, I have used a selector hook to get all the reducer and passed down the reducers as props to the required components
...ANSWER
Answered 2021-Mar-08 at 20:37Redux has a very useful Style Guide explaining all of the current best practices. There are a few recommendations on that list that are applicable to your example.
Use the React-Redux Hooks APIConnect More Components to Read Data from the StorePrefer using the React-Redux hooks API (
useSelector
anduseDispatch
) as the default way to interact with a Redux store from your React components.
Call useSelector Multiple Times in Function ComponentsPrefer having more UI components subscribed to the Redux store and reading data at a more granular level. This typically leads to better UI performance, as fewer components will need to render when a given piece of state changes.
When retrieving data using the
useSelector
hook, prefer callinguseSelector
many times and retrieving smaller amounts of data, instead of having a single largeruseSelector
call that returns multiple results in an object.
You definitely want to use useSelector
. Rather than selecting everything in the parent and passing it down, your Route
render components should take no props and get everything that they need from Redux themselves.
