Programming Flutter: SelectionPage referenced before written (page 180)
On page 180 of the PDF the reader is instructed to update the _fetchComic() method inside a SelectionPage widget. However, SelectionPage has not been written yet; it is not created until page 187.
This may have been caused by rearranging sections, so that the caching section used to be after adding selection, but now comes before it.
