Whether focused widgets should show a focus indicator.
A pointer press hides the indicator until the next keyboard input. Lone modifier and lock keys do not count, nor do Control, Meta, Super, or Hyper shortcuts, nor Alt shortcuts outside macOS. Key repeat does. Focus moved in code keeps the current visibility.
This follows the pointer and keyboard part of CSS :focus-visible. It does
not copy the text-input exception: a text field focused by a pointer does
not show an indicator. Style any focus, including that case, with
onFocused.
FocusHighlightStrategy.alwaysTraditional always shows indicators, and FocusHighlightStrategy.alwaysTouch never does. A FocusHighlightStrategy change that leaves FocusManager.highlightMode unchanged applies on the next rebuild.
Tracking starts on first use. Call ensureInitialized at startup when a pointer press can happen before the first Mix widget builds.
