Labels: tool,platform-windows,a: build,has reproducible steps,P2,team-tool,triaged-tool,found in release: 3.24,found in release: 3.27

### Steps to reproduce

Create and build template project

1. `flutter create flutter_project`
2. `cd flutter_project`
3. `flutter pub add material_symbols_icons`
4. Apply patch below
5. `flutter build windows --tree-shake-icons`
6. View build assets `build\windows\x64\runner\Release\data\flutter_assets\packages\material_symbols_icons\lib\fonts`

        // the application has a purple toolbar. Then, without quitting the app,
        // try changing the seedColor in the colorScheme below to Colors.green
        // and then invoke "hot reload" (save your changes or press the "hot
        // reload" button in a Flutter-supported IDE, or press "r" if you used
        // the command line to start the app).
        //
        // Notice that the counter didn't reset back to zero; the application
        // state is not lost during the reload. To reset the state, use hot
        // restart instead.

        // This works for code too, not just values: Most code changes can be
        // tested with just a hot reload.

  // how it looks.

  // case the title) provided by the parent (in this case the App widget) and
