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.

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"`

[@shahbaz17](https://github.com/shahbaz17) for android, I am getting this error on my app(not in flutter firebase example).

```
W/b3auth_firebase(26043): Accessing hidden method Ljava/lang/invoke/MethodHandles$Lookup;-><init\>(Ljava/lang/Class;I)V (unsupported, reflection, allowed)
E/flutter (26043): [ERROR:flutter/runtime/dart_vm_initializer.cc(41)] Unhandled Exception: PlatformException(error, null, null, null)
E/flutter (26043):#0 StandardMethodCodec.decodeEnvelopepackage:flutter/…/services/message_codecs.dart:653

E/flutter (26043):\<asynchronous suspension\>E/flutter (26043):
```

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