[WIP] Update samples deps and platform dirs

[filiph]

This should bring all templates and samples to the current Flutter & Dart stable.

Flutter 3.32.4 • channel stable • https://github.com/flutter/flutter.git
Framework • revision 6fba2447e9 (6 hours ago) • 2025-06-12 19:03:56 -0700
Engine • revision 8cd19e509d (9 hours ago) • 2025-06-12 16:30:12 -0700
Tools • Dart 3.8.1 • DevTools 2.45.1

The process:

• for each sample and template
  • edit pubspec.yaml to read sdk: ^3.8.0
  • flutter pub upgrade --major-versions
  • rm -rf ios android web windows macos linux && flutter create . --platforms android,ios,web,windows,macos,linux (except only use the platforms that the given sample uses)
    • may need to use --project-name xyz if the directory doesn't match the name
  • dart run flutter_launcher_icons (if used by the sample)
  • go through all changes and verify that nothing is lost
  • try building sample for various platforms and verify it runs
  • run tests
  • dart format .

Oh, I see, the CI fails before it even starts with:

subosito/flutter-action@395322a6cded4e9ed503aebd4cc1965625f8e59a is not allowed to be used in flutter/games. Actions in this workflow must be: within a repository that belongs to your Enterprise account, created by GitHub, verified in the GitHub Marketplace, or matching the following:

At first I thought the CI action doesn't start because I have [WIP] in the title.

I'm guessing the "not allowed" failure is an org issue and I can't really address it myself. (subosito/flutter-action seems to me like a hard requirement for CI/CD of this repo, unless there's another Flutter GH action of course).

I'll keep working on the upgrade in the meantime.

Ok, @domesticmouse, I think I've migrated everything (except samples/ads, which is in #118 and I can get to it next).

Let me know if I can do anything about the subosito/flutter-action failure.

We are working on it, promise.
