Listen for browser dismissal at the Expo

In my app created with expo react native, I have a scenario where the user is navigated to a URL using a WebBrowser. Is there a way for me to detect when the user closes or dismisses this WebBrowser and trigger a specific function accordingly?

Answer №1

To tackle this issue, I opted for an alternative approach using an authentication session method (openAuthSessionAsync) instead of the traditional web browser function (openBrowserAsync). By employing an authentication session, a promise is generated and the system continuously checks if the window has been closed by the user every second. If it detects closure, the promise resolves with { type: 'cancel' }.

Answer №2

Using openBrowserAsync :

const response = await WebBrowser.openBrowserAsync(url);
if (response && response.type === "cancel") {
  console.log('User closed the browser');
}
