Could not find the pub cache. No `LOCALAPPDATA` environment variable exists.

Note:Modify according to the first issue in Issues,otherwise, there will be another error message.
Setting up LOCALAPPDATA and PUB_CACHE still results in an error.

Code:

final importerResult = Process.runSync(
dartExec.toFilePath(),
[
'run',
'--enable-experiment=native-assets',
'flutter_scene_importer:import',
'--input',
inputFilePath,
'--output',
outDir.uri.resolve(outputFileName).toFilePath(),
'--working-directory',
buildInput.packageRoot.toFilePath(),
],
);
if (importerResult.exitCode != 0) {
throw Exception(
'Failed to run flutter_scene_importer:import command in build hook (exit code ${importerResult.exitCode}):\nSTDERR: ${importerResult.stderr}\nSTDOUT: ${importerResult.stdout}');
}

Attempt:
I printed out the parameters which are equivalent to the following command:

dart run --enable-experiment=native-assets flutter_scene_importer:import --input ../assets_src/fcar.glb --output E:\FlutterProject\flutter-demo01\flutter_scene-master\examples\flutter_app\build\models\fcar.model --working-directory E:\FlutterProject\flutter-demo01\flutter_scene-master\examples\flutter_app\

It was successfully executed in CMD.

Does the environment you run in have a LOCALAPPDATA environment setting?
(I think you can see that by writing set LOCALAPPDATA on the command line,
or maybe printing Process.environment["LOCALAPPDATA"] before doing the runSync.)

The includeParentEnvironment parameter to runSync should default to true, so if it's not there, maybe it's missing in the parent environment.

This command works fine in PowerShell or Cmd, Why not in Process. runSync, which should be flawed, Or the logic of the windows platform。
I'm just learning about the framework, it's too complicated for me to debug the Sdk, hopefully I can optimize it in the new version
