Commission<T> class

This class inherit from Computed and provide a function to set property 'value'

Inheritance
Mixed in types

Constructors

Commission({required T reader(), required void writer(T val), Validator? validator})
Create a computed can writeable

Properties

Check value has updated
no setterinherited
oldValue → T
The old value if has change
no setterinherited
onError → (void Function(Object error, StackTrace stack)?)
Function called if there are error in procession calculator
finalinherited
peek → T
The current value but ignore check depend on in Computed context
no setterinherited
rateLimit ↔ int
Only notify change and rebuild after a number period (millisecond)
getter/setter pairinherited
reader → T Function()
Function used to compute value
final
rebuildCount → int
Number times of calculator was called
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
stream → Stream<T>
Create a broadcast stream to listen value changes.
no setterinherited
subcriptions → List<Subscription>
The current subscription listen on to update computed
no setterinherited
valid → bool
Validate status
no setterinherited
validStatus → ValidateStatus
Get current status of validating process
no setterinherited
value ↔ T
The current value, if value called in a computed context, it will set Computed is depend on this
getter/setter pairinherited-getteroverride-setter
writer → void Function(T val)
Function used to update value
final

Methods

call() → T
inherited
changed(Function callback) → Subscription
Listen on value changed then run callback
inherited
dispose() → void
Remember close a computed if you don't need it to avoid it auto rebuild
inherited
listen(Function callback) → Subscription
Listen on value changed then run callback, it also run callback in first time
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
notify() → void
Notify to observers are listen on this observable
inherited
pause() → void
Temporary pause rebuild value if there are an observable changed
inherited
resume() → void
Resume and rebuild value after paused
inherited
setError(String? msg) → void
Manual set error, used to update error message by validate outsite
inherited
toString() → String
A string representation of this object.

Operators

operator ==(Object other) → bool
The equality operator.
