deactivate() → void
Called when this object is removed from the tree. [...]
debugFillProperties(DiagnosticPropertiesBuilder properties) → void
Add additional properties associated with the node. [...]
inherited
didChange(T newValue) → void
Updates this field's state to the new value. Useful for responding to child widget changes, e.g. Slider's Slider.onChanged argument. [...]
didChangeDependencies() → void
Called when a dependency of this State object changes. [...]
@mustCallSuper, @protected, inherited
didUpdateWidget(covariant InputField<T> oldWidget) → void

initState() → void
Initializes the input field by automatically registering itself to an InputForm ancestor (if there is one). [...]
@mustCallSuper
isEnabled() → bool
noSuchMethod(Invocation invocation) → dynamic

inherited
reassemble() → void
Called whenever the application is reassembled during debugging, for example during hot reload. [...]
@mustCallSuper, @protected, inherited
reset() → void

setValue(T newValue) → void
Sets the value associated with this form field. [...]
@protected
toDiagnosticsNode({String name, DiagnosticsTreeStyle style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep. [...]
inherited
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
Returns a string representation of this object.
inherited
toStringShort() → String
A brief description of this object, usually just the runtimeType and the hashCode. [...]
inherited
updateKeepAlive() → void
Whenever wantKeepAlive should change then updateKeepAlive must be called.
validate() → bool
