Is this package really not needed anymore? (And why?)

[JeffreyVanelderenACA]

React-native-modal still references to use this package in their ReadMe

@JeffreyVanelderenACA Thanks for letting me know. I'll look at testing this on the latest RN version, but likely in the New Year. I've a lot of different on-going projects that require my attention.

I had the same feeling as @JeffreyVanelderenACA, I was looking for an alternative but could not find any.

Any news?

I found a solution that seemed to work pefectly for me here: https://github.com/facebook/react-native/issues/23693#issuecomment-1207483253

It essentially boils down to - load a full-size view component at your app root, then get the dimensions from the onLayout prop's call argument e.nativeEvent.layout.

Here's a minimal TypeScript hook for ease of use:

import React, { useContext, useState } from "react";
import { Dimensions, LayoutRectangle, View } from "react-native";

type LayoutSize = Pick<LayoutRectangle, "width" | "height">;
const ScreenDimensionsContext = React.createContext<LayoutSize | null>(null);

export const useActualDimensions = () => {
  const dimensions = useContext(ScreenDimensionsContext);
  if (!dimensions) throw new Error("useDimensions hook must be used inside provider");
  return dimensions;
};

interface ScreenDimensionsProviderProps {
  children: React.ReactNode;
}
export function ActualDimensionsProvider({ children }: ScreenDimensionsProviderProps) {
  const [dimensions, setDimensions] = useState<LayoutSize>(Dimensions.get("window"));
  return (
    <ScreenDimensionsContext.Provider value={dimensions}>
      <View style={{flex: 1}} onLayout={(e) => setDimensions(e.nativeEvent.layout)}>
        {children}
      </View>
    </ScreenDimensionsContext.Provider>
  );
}
