/Javascript/React/Type '{ GlobalState: any; Dispatch: React.Dispatch<any>; }' is not assignable to type 'null'

Type '{ GlobalState: any; Dispatch: React.Dispatch<any>; }' is not assignable to type 'null'

Type '{ GlobalState: any; Dispatch: React.Dispatch; }' is not assignable to type 'null'

Since we have the useReducer hook, most of the time we do not need to use redux, or any other redux-like libraries.

To fix the issue with types, you need to define a ContextType.
===========
interface ContextType {
  state: {
    searchFilter: string[];
    dataRows: DataRow[];
  };
  dispatch: React.Dispatch<{ type: string; value: unknown }>;
}
========
To create your store context you can use the following. (We allow it to be null, so we do not have to deal with initial value when creating the context. The consumer will need to make sure that the context has been defined - see few lines below)
===============
const store = createContext<ContextType | null>(null);
===============
You can then create your useStore hook to access data from the store.
============
function useStore() {
  const value = React.useContext(store);
  if (!value) throw new Error("useStore needs to be within StateProvider");
  return value;
}
