textScaleFactor property
- @Deprecated('Use WidgetTester.platformDispatcher.textScaleFactor instead. ' 'Deprecated to prepare for the upcoming multi-window support. ' 'This feature was deprecated after v3.9.0-0.1.pre.')
- @override
override
The system-reported text scale.
Accessing this value returns the value contained in the
PlatformDispatcher singleton, so instead of getting it from here, you
should consider getting it from
WidgetsBinding.instance.platformDispatcher
instead (or, when
WidgetsBinding
isn't available, from PlatformDispatcher.instance). The
reason this value forwards to the PlatformDispatcher is to provide
convenience for applications that only use a single main window.
This establishes the text scaling factor to use when rendering text, according to the user's platform preferences.
The onTextScaleFactorChanged callback is called whenever this value changes.
See also:
- WidgetsBindingObserver, for a mechanism at the widgets layer to observe when this value changes.
