Describe the bug
'RenderBox was not laid out' was thrown.
To Reproduce
Steps to reproduce the behavior:
The code I wrote was below
(just to show login form)
import 'package:flutter/material.dart';
import 'package:flutter_gen/gen_l10n/app_localizations.dart';
import 'package:flutter_login/flutter_login.dart';
class LoginScreen extends StatelessWidget {
@override
Widget build(BuildContext context) {
return FlutterLogin(
onLogin: handleAuthUser,
onRecoverPassword: handleRecoveryPassword,
onSignup: handleSignup,
); // FlutterLogin
}
>> Future<String> handleAuthUser(LoginData data) {}
>> Future<String> handleRecoveryPassword(String data) {}
>> Future<String> handleSignup(LoginData data) {}
}

And when I start the app, an error was thrown
$ flutter run
Screenshots
I can see the error message below

After some debugging i found out that this error is being thrown here:
flutter_login/lib/src/widgets/auth_card.dart
Line 280 in 2fe68e4
If we comment out this
CustomPageTransformer() we don't get the error anymore. However, this PageTransformer controls the effect when navigation from login page to password reset page.
I have tried some things but i cant seem to find why this PageTransformer is causing issues. I think it has something to do with the parent width and height but i'm not sure.
I'm also seeing this for 1.1.0 in a fresh project where I simply add the example implementation. Is there a workaround that does not include hacking the library?
Attaching my sample project.

At this moment there is no work around besides commenting out the CustomPageTransformer() in the library. Since commenting this out means removing the animation between the different login and signup cards I don't want to remove it. I'm still searching for a solution that doesn't involve removing the animation.
I see. I'll keep an eye open if I stumble into something. I reverted to 1.0.15 and it works great.
Hello all,
is there any new information on this already?
Or a workaround :)?
Hi all,
there are some news on the issue?
Unfortunately, I have encountered even bigger problems with CustomPageTransformer call in my project. It is causing indeterminate memory errors, causing the whole application to crash.
RuntimeError: memory access out of bounds
It took me quite some time to discover the real cause, and I am still not sure under which conditions the problem surfaces but commenting that one line of code in auth_card.dart definitely solves the problem. The exception is triggered upon switching between login page and recover password page; sometimes during the 2nd switch, sometimes 20th. Interestingly, I didn't observe it with the example project, but in many other project formations I used, it shows up.
Hi,
is there any update on this issue?
I have added the following parameter which can be used to disable the CustomPageTransformer: disableCustomPageTransformer: true
