So when I am trying to integrate web3auth in my flutter application. When I try to log in the dialog box disappears within a second.

RPReplay_Final1672815623.MP4

When I tried the flutter code in the examples repository, changed the google info.plist, bundle id, client id from web3auth, and verifier name, I get this error
"Cannot initialize TypeOfLogin from invalid String value TypeOfLogin.jwt"

Hey @ritvij14

To test, could you pass the hard-coded usernames and password values to the login function? It looks like the form is getting reloaded. Hence the pop is getting closed.

Have you tried running the flutter firebase example app as it is? And let me know if the problem remains the same.

Next, update with your config details, keeping the login flow the same. And let me know if you're able to login or not.

Hi @shahbaz17

I tried out both the things, so just sent hard coded email and password to the function, then executed the firebase login and used the idToken in web3auth, same issue as before, the dialog disappears within a second.

For the example repository, I ran it just as it without changing anything and I get this error on pressing the login button

Hey @ritvij14

So is it for all Flutter apps or just the web3auth apps? I would need to know more about this error. Would you be able to share more from the debugger screen for this login error?

@shahbaz17 this is happening only for the flutter firebase example app from the examples repo of web3auth

here is the complete error log when I run it on my iPhone

Hey @ritvij14

Could you run pod install inside ios folder of the project and try running again?

ritvij14 Jan 10, 2023

@shahbaz17 just did, same issue. Its m1 chip so in all my flutter projects, I did arch -x86_64 pod install. Normal pod install gives me issues in all flutter projects. But even with normal pod install, no change, same error.

@shahbaz17 for android, I am getting this error on my app(not in flutter firebase example).

It says the error is in the flutter package of web3auth in the line where it is calling the method channel function.

Was having the same problem. Fine on emulator but dissapearing popup on device. I Set the ios build target to 13 in project.pbxproj and solved.

@shahbaz17 the redirect URL in my code and in the whitelist is w3a://com.example.w3aflutter/auth. Also this is from both the android device and emulator. Same error in both the cases.

Hey @ritvij14

Can you just add w3a://com.example.w3aflutter as whitelist on dashboard?
