Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
buttonPosition(int buttonNumber) → double
Gives each individual button position dynamically based on their index
controlButtonPosition(bool previousButton) → double
Not used with current setup Do not delete in case of future need
deleteState() → Future<void>
Delete nevigator state Resets page index for return to navigator at default start index
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
inherited
getPreviousPageIndex() → List<int>?
Gets last index for page transition animation Index.first = previousPage Index.last = currentPage
lineHeight() → double
Dynamically creates line length based on lowest button Lowest button is based on page index length
Navigates directly to page index Skips pages based on users choice of direct navigation
Positions subtitle text precisely to right of line
Positions major section title to left of line

inherited
previousPage() → void
Handles previous page logic Causes scrolling page controller to animate to previous page
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.

saveState() → Future<void>
Checks persistant storage for saved value Overwrites if it exists and creates it if it does not
setallowDirectNavigation(bool parameter) → void
Set whether user can tap buttons to go directly to index
setPages(List<SliverChildBuilderDelegate> inputPages) → void
Sets list of pages Builds layouts by page contents in the form of SliverChildBuilderDelegate
