resolve method

@override Source resolve(String relPath)

Resolves the given relative path to a Source object.

This method normalizes the relative path, checks if the file exists, reads its content, and returns a Source object containing the file's URI and content.

Throws an exception if the file does not exist.

Implementation

@override
Source resolve(String relPath) {
  final file = fileSystem.file(_resolvePath(relPath));
  if (!file.existsSync()) {
    throw Exception('Template file not found: $relPath');
  }

  final content = file.readAsStringSync();
  return Source(file.uri, content, this);
}
