Properties

autovalidateMode → AutovalidateMode
Used to enable/disable this form field auto validation and update its error text.
finalinherited
builder → FormFieldBuilder<T>
Function that returns the widget representing this form field.
finalinherited
enabled → bool
Whether the form is able to receive user input.
finalinherited
errorBuilder → FormFieldErrorBuilder?
Function that returns the widget representing the error to display.
finalinherited
forceErrorText → String?
An optional property that forces the FormFieldState into an error state by directly setting the FormFieldState.errorText property without running the validator function.
finalinherited
hashCode → int

no setterinherited
initialValue → T?
An optional value to initialize the form field to, or null otherwise.
finalinherited
key → Key?
Controls how one widget replaces another widget in the tree.
finalinherited
onChange → ValueChanged<T?>?
Called whenever the form field changes.
final
onFieldSubmitted → ValueChanged<T?>?
Called whenever the form field is submitted.
final
onReset → VoidCallback?
An optional method to call when the form field is reset via FormFieldState.reset.
finalinherited
onSaved → ValueChanged<T?>?
An optional method to call with the final value when the form is saved via FormState.save.
finalinherited
requirementLevel → ZetaFormFieldRequirement?
The requirement level of the form field.
final
restorationId → String?
Restoration ID to save and restore the state of the form field.
finalinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
