no setterinherited
hashCode → int

no setterinherited
hasListeners → bool
Whether any listeners are currently registered.
no setterinherited
isSubmitted → bool
Returns true if the form has been submitted.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
states → Set<InputFormState>
The current states of this form.

Methods

activate(Object tag) → void
Sets the field bound with the tag as active.
addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
call<T extends Object>(Object tag) → FieldController<T>
Gets the FieldController bound with the tag.
contains(Set<InputFormState> states) → bool
Returns true if the form states contains any of the states.
deactivate(Object tag) → void
Sets the field bound with the tag as inactive.
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).
override
getField<T extends Object>(Object tag) → FieldController<T>?
Gets the FieldController bound with the tag.
getValue<T extends Object>(Object tag) → T?
Gets the value of the field bound with the tag.
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notifyListeners() → void
Call all the registered listeners.
inherited
remove(Object tag) → void
Removes the field bound with the tag.
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 form to initial state.
setInitialValues(Map<Object, Object?> initialValues, {bool notify = true}) → void
Sets the initial values for the form.
setSubmitted(bool isSubmitted) → void
Sets the value for isSubmitted of the form and each 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({Set<Object>? tags, bool notify = true}) → bool
Validates the form.

Operators

The equality operator.
