Methods

addListener(VoidCallback listener) → void
Register a closure to be called when the object changes.
inherited
build({required Widget builder(Basetro<T> state, BuildContext context)}) → Widget

Available on Basetro<T>, provided by the BasetroBuilderTools extension

Creates a MastroBuilder widget for this state object.
compute<R>(R calculator(T value)) → Mastro<R>
Creates a computed state that depends on this state.
debugLog([String? name]) → void

Available on Basetro<T>, provided by the BasetroDebug extension

Logs state changes to the console.
dependsOn(Basetro other) → void
Adds a dependency on another state.
dispose() → void
Discards any resources used by the object. After this is called, the object is not in a usable state and should be discarded (calls to addListener will throw after the object is disposed).
override
modify(void modify(Mutable<T> state)) → void
Modifies the state with a callback.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notify() → void
Notifies listeners of state changes.
override
notifyListeners() → void
Call all the registered listeners.
inherited
notifyObservers() → void
Notifies all observers of state changes.
observe(String key, void callback(T value)) → void
Adds an observer callback.
removeDependency(Mastro other) → void
Removes a dependency.
removeListener(VoidCallback listener) → void
Remove a previously registered closure from the list of closures that are notified when the object changes.
inherited
removeObserver(String key) → void
Removes an observer.
setValidator(bool validator(T value)) → void
Sets a validation function for value changes.
toggle() → void

Available on Basetro<bool>, provided by the MastroBoolTools extension

Toggles the boolean value.
