help me!!!

the function below in class VideoFragment of 'sample' module:
public static Fragment build(String url) {
return VideoFragment_.builder()
.url(url)
.build();
}
but I can't find builder()、url(url)、build() in current class.

Start in the sample module at class VideoFragment and inspect the build(String url) entry point, then search the project for VideoFragment_ and the builder, url, and build methods. Done would require documenting where these members come from or clarifying the sample code so a reader can locate them.
