resolvePackageExecutable function

Future<String> resolvePackageExecutable(String packageUri, [ String? executableName ])

Resolves the absolute path to an executable in bin/ given a packageUri and an optional executableName.

If executableName is omitted, defaults to the package name (the first path segment of packageUri).

Throws a StateError if the executable file does not exist.

Implementation

Future<String> resolvePackageExecutable(
  String packageUri, [
  String? executableName,
]) async {
  final pkgDir = await resolvePackageDirectory(packageUri);
  final exec = executableName ?? Uri.parse(packageUri).pathSegments.first;
  final binFile = File(p.join(pkgDir, 'bin', '$exec.dart'));
  if (!binFile.existsSync()) {
    throw StateError(
      'Executable not found at "${binFile.path}". '
      'Ensure bin/$exec.dart exists in package "$packageUri".',
    );
  }
  return p.normalize(binFile.path);
}
