Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited

debugFillProperties(
DiagnosticPropertiesBuilder properties) → void -
Add additional properties associated with the node.
inherited
-
dispose(
) → void -
Discards any resources used by the object. After this is called, the
object is not in a usable state and should be discarded (calls to
addListener will throw after the object is disposed).
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
onChanged(
String? value, {bool notify = false}) → void -
Sets the
valueof the field.override -
onUpdate(
void listener(String? value)) → void -
Callback for listening to changes in the field.
inherited
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
reset(
) → void -

-
setError(
InputFieldError error, {bool notify = true}) → void -
Sets the
errorof the field.inherited -
setInitialValue(
String? value, {bool notify = false}) → void -
Sets the initial
valueof the field.inherited -
setSubmitted(
bool value) → void -
Sets the
valuefor isSubmitted of the field.inherited -
setValidators(
Set< InputFieldValidator> validators) → void -
Sets the
validatorsfor the field.inherited -
setValue(
String? value, {bool notify = true}) → void -
Sets the
valueof the field.override -
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 -

inherited
-
toStringShort(

hashCode.
