ThemeData accentColor deprecated in Flutter 3.10.0

[gmckesey]

Projects including flutter_neomorphic will not build as of Flutter 3.10.0 due to the accentColor parameter in the ThemeData constructor being deprecated. The line at issue is app.dart:89.

To temporarily solve this issue run in your project directory -

"flutter downgrade"

then accept the changes. You might have a few issues (const keywords, or others) but they are solvable by you and not the package. This should suffice until they fix this issue.

Not sure who to contact about it, but I think the issue may be related to the use of Theme.of(context).accentColor in the file "app,dart". And anywhere else it may potentially be used. That usage was removed from Flutter completely and thus throws the error. The new usage would be "Theme.of(context).colorScheme.secondary" instead. I'll copy-paste this reply to the other thread I found on the topic too, in the hopes someone will see it and make the change. I'd have done it myself really quick to see if it solved anything but I'm not listed as a collaborator lol

Here is my fix, which updates the SDK constraints to support Flutter >= 3.10.0. It works as expected:
