Failed to compile due to too old dependencies on Flutter

[NineWoranop]

Hello,

I failed to get the dependencies on this flutter example. The dependencies are too old. They are no longer there for compile.
Could you please help me to upgrade your example if you have time?

Simply changing the dependency versions make the repo work for me. Below is my setup for pubspec.yaml:

environment:
  sdk: ">=3.1.2 <4.0.0"

dependencies:
  flutter:
    sdk: flutter
