ProgressTracker<T> class
- Inheritance

- Object
- ChangeNotifier
- ProgressTracker
Constructors
-
ProgressTracker(FutureOr<
num> total, Object key) - Creates
- ProgressTracker.ratio([Object? key])
- Instead of counting towards an arbitrary count, we'll base the counter on a percent and the caller will make sure to send the appropriate ratios
Properties
- hashCode → int
-
The hash code for this object.
no setterinherited
- hasListeners → bool
-
Whether any listeners are currently registered.

- isInProgress → bool

- key → Object?
-
final
- percent → double
-
Returns a percent completed, between 0 and 100
no setter
- percentText → String
-
Returns the completed percent in textual form, with a % sign
no setter
- progress → double

result
→ Future<
T> -
no setter
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- task → String?
-
no setter
- total → double?
-
The total number of units working towards. For percent/ratio based tracking, this will be 100
no setter
Methods
-
addListener(
VoidCallback listener) → void -
Register a closure to be called when the object changes.
inherited
-
complete(
[T? result]) → void - Marks this counter as complete
-
completeError(
[Object? error, StackTrace? stack]) → void - Marks this counter as complete
-
decrement(
) → void -
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
-
finishTask(
double progress, {String? newTask}) → void -
finishTaskRatio(
double progress, {String? newTask}) → void -
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
notifyListeners(
) → void -
Call all the registered listeners.
inherited
-
removeListener(
VoidCallback listener) → void -
Remove a previously registered closure from the list of closures that are
notified when the object changes.
inherited
-
reset(
) → void -
toString(
) → String -
A string representation of this object.
inherited
-
update(
double progress, {String? newTask, double? total}) → void -
updateRatio(
double ratio, {String? newTask}) → void -
updateTask(
String newTask) → void -
updateTotal(
double total) → void
Operators
-
operator ==(
Object other) → bool -
The equality operator.
