Firefox can't close redirect window #83
Description
Describe the bug
By default firefox wont close the redirect auth.html page and will give this warning
"Scripts may not close windows that were not opened by script."
Also having it open a new page and redirect to a random html page outside of the flutter app feels bad
GoogleSignIn can open a new window for signing in and than pass back the info directly to flutter without needing a external html page
Im wondering if there is a way for this auth package to do the same as I would like to perform the auth on my backend server and google and just pass back a token to confirm the season to the client.
Example from my tests
Google Sign in
static Future<String?> googleLogin() async {
final googleUser = await GoogleSignIn(
clientId: dotenv.env['GOOGLE_ClIENT_ID'],
scopes: [
'email'
]
).signIn();
if (googleUser == null) return null;
final googleAuth = await googleUser.authentication;
return "Access Token: ${googleAuth.accessToken} User ${googleAuth.idToken} ID ${googleUser.id} Display Name: ${ googleUser.displayName} AuthCode: ${googleUser.serverAuthCode} Image: ${googleUser.photoUrl}";
}Flutter_Web_Auth_2 code
static Future<String?> handleGoogleSignIn() async {
String uri =
kReleaseMode ? dotenv.env['PROD_API_URL']! : dotenv.env['DEV_API_URL']!;
uri = '$uri/auth/google/authorize';
final result = await FlutterWebAuth2.authenticate(
url: uri,
callbackUrlScheme: "my-custom-app",
);
final results = Uri.parse(result).queryParameters['token'];
return results;
}
}auth.html
<!DOCTYPE html>
<title>Authentication complete</title>
<p>Authentication will complete in around two seconds. If this does not happen automatically, please
close the window.
<script>
setTimeout(function(){
if (window.opener) {
window.opener.postMessage({
'flutter-web-auth-2': window.location.href
}, window.location.origin);
} else {
localStorage.setItem('flutter-web-auth-2', window.location.href);
}
window.close();
}, 2000);
</script>To Reproduce
