ReactiveString class
A specialized implementation of Reactive for String values.
It extends the Reactive class and provides specific functionality for String values. Use this class when you need a reactive String variable that can be observed for changes.
Constructors
- ReactiveString(String value, {bool enableHistory = false, int maxHistorySize = 50})
- Creates a new instance of ReactiveString with the initial value.
