kandi X-RAY | FontConstants Summary
UIFont's string-based API for choosing fonts is notoriously prone to typos and mistakes. Unfortunately, these often result in crashes or incorrect styles that aren't located until much later in development. FontConstants provides enum declarations and accessors for all fonts bundle with iOS. All fonts are marked with @available tags so that the Swift compiler can prevent you from using fonts not available on a version of iOS, watchOS, or tvOS that your app supports.

One such unit is 1/72 inch unless it is redefined by the UserUnit entry of the respective page (A positive number that shall give the size of default user space units, in multiples of 1 ⁄ 72 inch. The range of supported values shall be implementation-dependent. - ISO 32000-2, Table 31 — Entries in a page object).
Concerning your added question concerning the addition of text to your PDF:
The reason why the position where your text is drawn is not where you expect it to be drawn, is that the user space coordinate system has been transformed in the original content stream:

Answered 2021-Apr-02 at 14:31I had the problem on Landing Screen that it mess's the widget tree. Because didChangeDependancy method would be called more than one time and with any changes from the widget tree. the solution is to didChangeWidget instead of didChangeDependancy and change the navigation to offAndToNamed.
