nativeSpellCheckServiceDefined property
Whether the spell check service is supported on the current platform.
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 option is used by EditableTextState to define its SpellCheckConfiguration when spell check is enabled, but no spell check service is specified.
Implementation
bool get nativeSpellCheckServiceDefined => platformDispatcher.nativeSpellCheckServiceDefined;
