Whether this field should be automatically validated.
finalinherited
error → InputFieldError
The current error of this field.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
hasListeners → bool
Whether any listeners are currently registered.
no setterinherited
isDirty → bool
Returns true if the field has been modified.
no setterinherited
isSubmitted → bool
Returns true if the field has been submitted with setSubmitted.
no setterinherited
parent → FormController

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.
override
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(T? value, {bool notify = true}) → void
Sets the value of the field.
onUpdate(void listener(T? value)) → void
Callback for listening to changes in the field.
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
reset() → void
Resets the field to its initial value.
inherited
setError(InputFieldError error, {bool notify = true}) → void
Sets the error of the field.
setInitialValue(T? value, {bool notify = false}) → void
Sets the initial value of the field.
setSubmitted(bool value) → void
Sets the value for isSubmitted of the field.
setValidators(Set<InputFieldValidator> validators) → void
Sets the validators for the field.
setValue(T? value, {bool notify = true}) → void
Sets the value of the field.
toDiagnosticsNode({String? name, DiagnosticsTreeStyle? style}) → DiagnosticsNode
Returns a debug representation of the object that is used by debugging tools and by DiagnosticsNode.toStringDeep.
override
toString({DiagnosticLevel minLevel = DiagnosticLevel.info}) → String
A string representation of this object.
inherited
toStringShort() → String
A brief description of this object, usually just the runtimeType and the hashCode.
inherited
validate({bool notify = true}) → bool
Validates the field.

Operators

operator ==(Object other) → bool
The equality operator.
