relativeToRoot static method
Converts an absolute file path to one relative to rootPath, with
forward slashes regardless of host OS — matching how paths are
referenced in Dart source, ignore/baseline config, and JSON/SARIF
output.
Implementation
static String relativeToRoot(String filePath, String rootPath) {
return p.relative(filePath, from: rootPath).replaceAll(r'\', '/');
}
