RxFormFieldBuilderState<B extends RxBlocTypeBase, T, R extends RxFormFieldBuilder<B, T>> class

RxFormFieldBuilderState is the field state provided to the builder function of RxFormFieldBuilder.

it Contains several useful fields: bloc, value, error and showError;

The bloc field gives you access to the RxBloc from which the field state is derived, it should be mostly used in order to fire off events towards the bloc, in response to user interaction with the form field.

The value field is the most current value from the state stream.

The error field holds the most recent error from the state stream, !it gets assigned null if a value gets emitted by the state stream.

The showError field provides the latest boolean value from the showErrorState stream, use it to determine when you should start showing errors to the user.

!The showErrorState stream must never emmit an error

Properties

bloc → B
The bloc field gives you access to the RxBloc from which the field state is derived, it should be mostly used in order to fire off events towards the bloc, in response to user interaction with the form field.
no setter
context → BuildContext
The location in the tree where this widget builds.
no setterinherited
error → String?
The error field holds the most recent error from the state stream, !it gets assigned null if a value gets emitted by the state stream.
no setter
hashCode → int
The hash code for this object.
no setterinherited
mounted → bool
Whether this State object is currently in a tree.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
showError → bool
The showError field provides the latest boolean value from the showErrorState stream, use it to determine when you should show errors to the user.
no setter
value → T?
The value field is the most current value from the state stream. If everything is done right, this should basically never be null, you should provide initial value to the state stream from the implementation of the bloc.
no setter
widget → R
