🐛 [firebase_ui_auth] Version 1.4.0 is causing compilation error

[outdoorapps]

The recent changes in version 1.4.0 are causing the following compilation error:

../../.pub-cache/hosted/pub.dev/firebase_ui_auth-1.4.0/lib/src/screens/profile_screen.dart:393:19: Error: Cannot invoke a non-'const' constructor where a const expression is expected. Try using a constructor or factory that is 'const'. const Row( ^^^

The const keyword wasn't there in version 1.3.0.

Thanks for the report @outdoorapps I am unable to replicate it using the plugin example and running on Android. Can you provide dependencies you are using ?

[outdoorapps]

I opened a blank project to test things out with bare minimum dependencies like the below.

dependencies:
  flutter:
    sdk: flutter

  firebase_core: ^2.12.0
  firebase_ui_auth: ^1.4.0
  cupertino_icons: ^1.0.2

The first time it compiled ok but if I use the ProfileScreen widget like this:

  @override
  Widget build(BuildContext context) {
    return const ProfileScreen();
  }

It will give the forementioned error.

Taking a closer look to the source code, in profile_screen.dart, on line 393-400, it has:

const Row(
              mainAxisAlignment: MainAxisAlignment.center,
              children: [
                LoadingIndicator(size: 16, borderWidth: 0.5),
                SizedBox(width: 16),
                Text('Waiting for email verification'),
              ],
            )

Somehow the const keyword sneaked into the source code because not even const Row() would work currently on flutter.

Confirming I'm also having this issue.

I'm also having the same issue. Row doesn't have a const constructor.

Attempting to submit a fix for this, how open source of me 😄. If people want to fix it themselves they can move the const down in the code of the file where the error was specified (profile_screen.dart):

            Row(
              mainAxisAlignment: MainAxisAlignment.center,
              children: const [
                LoadingIndicator(size: 16, borderWidth: 0.5),
                SizedBox(width: 16),
                Text('Waiting for email verification'),
              ],
            )
