   Thanks @makri-aymen for opening the issue.

   Yes, I'm aware of this, it will probably until next weekend (Sunday, Aug 23), until the compatible version is released.

   Meanwhile, if you really must be on version 3.47 before that you can try using the MaterialUiCompatibilityBridge mentioned in the release notes. Although I have not tested if that actually works as claimed in the release notes.

   I want to bring a number of other improvements and changes to the package at the same time. Since decouple bump recommends bumping major version of packages, I want to include a few other things that may be minor breaking at the same time. I don't want to do two major releases after each other. I might put out a dev/pre release with only the decouple bump first. That should make a fix available sooner.

   Bridging the migration gap

   To facilitate bridging the gap as the ecosystem migrates to the new standalone design libraries, material_ui and cupertino_ui ship with migration utilities. The MaterialUiCompatibilityBridge allows your application to migrate to the standalone packages immediately, even if some of your package dependencies are still using legacy core SDK imports.

   For example, you can wrap your app in the compatibility bridge:

   import 'package:material_ui/material_ui.dart';
   
   void main() {
     runApp(const MyApp());
   }
   
   class MyApp extends StatelessWidget {
     const MyApp({super.key});
   
     @override
     Widget build(BuildContext context) {
       return MaterialApp(
         theme: ThemeData(
           colorScheme: ColorScheme.fromSeed(seedColor: const Color(0xFF6750A4)),
         ),
         builder: (BuildContext context, Widget? child) {
           return MaterialUiCompatibilityBridge(child: child!);
         },
         home: const HomeScreen(),
       );
     }
   }

   @makri-aymen for info version 5.0.0 of FlexSeedScheme has been released it closes this issue.

   It was substantial work to get the package to this level as I included moving to also opting in on Dart 3.13, more tests, improve docs, set up the package for agentic dev with both Codex and Claude.
   Internal dev skills as well as skill for consumers that can be given to agents if needed.

   Also fixed some small bugs.

   The change log: https://pub.dev/packages/flex_seed_scheme/changelog
   A lot of changes, but mostly just version hygiene https://github.com/rydmike/flex_seed_scheme/pull/25/commits
