How start from last view position? #
This method allows you to keep the exact reading position even inside the chapter:
_epubController = EpubController(
// initialize with epub cfi string for open book from last position
epubCfi: 'epubcfi(/6/6[chapter-2]!/4/2/1612)',
);

// Attach controller
EpubView(
controller: _epubController,
);

// Get epub cfi string
// for example output - epubcfi(/6/6[chapter-2]!/4/2/1612)
final cfi = _epubController.generateEpubCfi();

// or usage controller for navigate
_epubController.gotoEpubCfi('epubcfi(/6/6[chapter-2]!/4/2/1612)');
