I'm having a problem while trying to create a build using Flutter 3.10.2, and as a result, I can't compile my project.

Target dart2js failed: Exception: ../../../.pub-cache/hosted/pub.dev/flick_video_player-0.5.0/lib/src/flick_video_player.dart:141:13:
Warning: Operand of null-aware operation '!' has type 'OverlayState' which excludes null.

  Internal Error: The compiler crashed when compiling this element.

The compiler is broken.

When compiling the above element, the compiler crashed. It is not
possible to tell if this is caused by a problem in your program or
not. Regardless, the compiler should not crash.

The Dart team would greatly appreciate if you would take a moment to
report this problem at http://dartbug.com/new.

Please include the following information:

• the name and version of your operating system,

• the Dart SDK build number (3.0.2), and

• the entire message you see here (including the full stack trace
  below as well as the source location above).

The compiler crashed: Crash when compiling:
type 'Null' is not a subtype of type 'FunctionType' in type cast

How did you fix this? I notice that when running flutter pub upgrade, I notice that web has a new version but can't upgrade due to a dependency constraint
