FormValues class

A form's in-progress values.

Runtime-shaped like ResourceRecord: the schema is only known at runtime, so this is a typed wrapper over a map rather than a generated model. It is immutable — set returns a new instance — so a provider's notifyListeners() always corresponds to a genuinely new object and a widget comparing old to new sees a difference.

Constructors

FormValues.initial(List<SchemaComponent> components, {Map<String, dynamic> from = const {}})

Seeds one value per named field in components: from (a record being edited) wins when it holds the key — including an explicit null, which is a value the user deliberately cleared — and a component's own default fills the gap only when from has no entry at all.

Properties

no setter

The hash code for this object.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

payloadFor(List<SchemaComponent> components) → Map<String, dynamic>

Builds a submission payload from the schema's declared field names, not from _values's keys — the client-side mirror of the server's "no rule, no validated key, no write". A key the schema does not declare, however it got into the value map, can never reach the server this way.

set(String name, Object? value) → FormValues

Over-eager on purpose: setting a field back to its initial value still marks it dirty rather than diffing against the seed. An extra field in the payload is cheap; silently dropping a real edit is not.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.

operator [](String name) → Object?
