body method

@override String body(String path, String baseName, String className)

Defines the actual body code. path is passed relative to lib, baseName is the filename, and className is the filename converted to Pascal case.

実際の本体コードを定義します。pathにlibからの相対パス、baseNameにファイル名が渡され、classNameにファイル名をパスカルケースに変換した値が渡されます。

Implementation

@override
String body(String path, String baseName, String className) {
  return """
