Reproduction Steps: Logout ignores allowedBrowsers and uses default browser (Firefox)
Preconditions
- Android device has Firefox installed and Google Chrome installed.
- Set Firefox as the system default browser:
- Android Settings → Apps → Default apps → Browser app → Firefox
- In the app’s Auth0 login setup, configure allowedBrowsers to exclude Firefox and allow only Chrome (and/or other non-Firefox browsers).
- Example intent: allowedBrowsers = [Chrome] (Firefox not included)
- Ensure the app is configured for Auth0 login/logout normally (callbacks and allowed URLs already set).
I have used allowedBrowsers to restrict firefox browser, adding only other browser list with google chrome.
Issue:
But if user has selected default browser as Firefox, App uses chrome instance to login, but when I press logout it loads the FireFox (Default) in app webview and load 'Not Found' Page. I think logout function does not consider the allowedBrowsers. we might need to add that parameter to there as well I guess.
Future<Credentials> login() async {
_logger.d('Logging in with Auth0');
try {
final webAuthScheme = Platform.isAndroid ? 'https' : scheme;
final response = await _auth0.webAuthentication(scheme: webAuthScheme).login(
scopes: {'openid', 'profile', 'email', 'offline_access'},
useHTTPS: true,
allowedBrowsers: Platform.isAndroid
? const [
// Chrome & Chrome Custom Tabs

: const []
);
Reproduction
- Launch the Android app.
- Start the Auth0 Login flow.
- Observe that login opens in Chrome (Custom Tab) even though the device default browser is Firefox (expected due to allowedBrowsers).
- Complete login successfully and return to the app.
- Trigger Logout from within the app (Auth0 logout flow).
- Observe which browser/webview is used to perform logout and what page loads.
