react-native-safe-area-context/src/InitialWindow.native.ts

A flexible way to handle safe area, also works on Android and web.

import type { Metrics } from './SafeArea.types';
import NativeSafeAreaContext from './specs/NativeSafeAreaContext';

export const initialWindowMetrics = (NativeSafeAreaContext?.getConstants?.()
  ?.initialWindowMetrics ?? null) as Metrics | null;

/**
 * @deprecated
 */
export const initialWindowSafeAreaInsets = initialWindowMetrics?.insets;
