Optimizations

Web SSR​

If you are doing server side rendering on the web you can use initialMetrics to inject insets and frame value based on the device the user has, or simply pass zero values. Since insets measurement is async it will break rendering your page content otherwise.

SafeAreaView​

If you can, use SafeAreaView. It's implemented natively so when rotating the device, there is no delay from the asynchronous bridge.

initialWindowMetrics​

To speed up the initial render, you can import initialWindowMetrics from this package and set as the initialMetrics prop on the provider as described in Web SSR. You cannot do this if your provider remounts, or you are using react-native-navigation.

import {
  SafeAreaProvider,
  initialWindowMetrics,
} from 'react-native-safe-area-context';

function App() {
  return (
    <SafeAreaProvider initialMetrics={initialWindowMetrics}>
      ...
    </SafeAreaProvider>
  );
}
