ToggleSheetDelegateValue<T> class

A delegate that always returns a constant, static value.

This is useful when the value controlling sheet behavior (e.g., barrierColor) is fixed and does not need to respond to dynamic state or controller input.

Typically used like this:

barrierColorDelegate: ToggleSheetDelegate.value(Colors.black.withOpacity(0.5))

⚠️ It is recommended to initialize this delegate as a final field (e.g., in your State class), not directly inside the build() method, to avoid unnecessary widget rebuilds.

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.
