pub get failed - no lower bound SDK constraint

[coastalgit]

After upgrade to Flutter 2 stable channel, I was unable to build a pro-icon package with version 8.11.0 from master, getting error when running flutter packages get:

pubspec.yaml has no lower-bound SDK constraint.
You should edit pubspec.yaml to contain an SDK constraint:

environment:
  sdk: '>=2.10.0 <3.0.0'

I found that the error is because of the pubspec.yaml file inside example folder. Change that to:

name: font_awesome_flutter_example
description: The Font Awesome Flutter Gallery

environment:
  sdk: ">=2.7.0 <3.0.0"
  
dependencies:
  flutter:
    sdk: flutter
  font_awesome_flutter:
    path: ../

flutter:
  uses-material-design: true

Thanks @droidzone - that resolved pub get.

Guys need help, tried your solution, still not working. Can you take a look at my pubspec.yaml?
