StatefulSheetDelegateValue<T> class

A delegate that holds a static value.

This delegate always returns the same fixed value regardless of the sheet state or controller.

Typically used when you want to provide a constant value for a property of the sheet that does not depend on the controller's state or animations.

⚠️ Important: You should create this delegate outside the widget's build method — ideally as a final field in a State class, or within a view model or other persistent scope. Avoid constructing it inline within build() to ensure consistency and performance.

Example:

final delegate = StatefulSheetDelegateValue<int>(value: 42);

Properties

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

value → T

The fixed value returned by this delegate.

final

Methods

getStaticValue() → T?

We need this method to get the value of the delegate if it is a static value. We want to avoid calling the function every time we need the value and we can use this method in init() to get the value of the delegate and store it in a variable.

inherited

getValue<StateType>(MultiStateSheetController<StateType> controller) → T?

inherited

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
