Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes. [...]
inherited
approveSelection(PrefixMatchState state, SuggestedDataWrapper data) → void
buildTextSpan({BuildContext? context, TextStyle? style, bool? withComposing}) TextSpan
Builds TextSpan from current editing value. [...]
override
calculateGlobalOffset(BuildContext context, Offset? localOffset, {double? dialogHeight, double? dialogWidth}) Offset?
