DragStep class

Step that will attempt to scroll another widget until it becomes visible.

Inheritance

Constructors

DragStep({required String? dx, required String? dy, required String testableId, Duration? timeout})

Properties

defaultStepTimeout → Duration
Returns the default timeout for the step. Steps that should respond quickly should use a relatively low value and steps that may take a long time should return an appropriately longer time.
no setterinherited
driver → OverrideWidgetTester
Returns the test driver that can be used to interact with widgets.
no setterinherited
dx → String?
The horizontal drag direction in device-independent-pixels. This may be a positive or negative number. The relative direction depends on the device's Left-to-Right configuration.
final
dy → String?
The vertical drag direction in device-independent-pixels. This may be a positive or negative number. The relative direction depends on the device's Up-to-Down configuration.
final
find → CommonFinders
Returns the finder that can be used to locate widgets.
no setterinherited
hashCode → int
The hash code for this object.
no setterinherited
runtimeType → Type
A representation of the runtime type of the object.
no setterinherited
stepId → String
no setteroverride
testableId → String
The id of the Testable widget to interact with.
final
timeout → Duration?
The maximum amount of time this step will wait while searching for the Testable on the widget tree.

Methods

execute({required CancelToken cancelToken, required TestReport report, required TestController tester}) → Future<void>
Executes the test step. If the scrollableId is set then this will get that Scrollable instance and interact with it. Otherwise, this will attempt to find the first Scrollable instance currently in the viewport and interact with that.
override
getBehaviorDrivenDescription(TestController tester) → String
Gets the most appropriate BDD string based on the values set on the step.
override
log(String message, {required TestController tester}) → void
Logs a message and posts it as a status update to the TestRunner.
inherited
noSuchMethod(Invocation invocation) → dynamic
Invoked when a nonexistent method or property is accessed.
inherited
postStepSleep(Duration duration) → Future<void>
Gives the test step an opportunity to sleep after the step has been executed. Steps that do not interact with the application may choose to override this and reduce or elimate the delay.
inherited
preStepSleep(Duration duration) → Future<void>
Gives the test step an opportunity to sleep before the step has been executed. Steps that do not interact with the application may choose to override this and reduce or elimate the delay.
inherited
sleep(Duration duration, {required Stream<void>? cancelStream, bool error = false, String? message, required TestController tester}) → Future<void>
Sleeps for the defined Duration. This accept an optional cancelStream which can be used to cancel the sleep. The error flag informs the sleeper about whether the duration is a standard duration or an error based timeout.
inherited
toJson() → Map<String, dynamic>
Converts this to a JSON compatible map. For a description of the format, see fromDynamic.
toString() → String
Returns the string encoded JSON representation for this class. This will remove all null values and empty collections from the returned string.
inherited
waitFor(dynamic testableId, {required CancelToken cancelToken, required TestController tester, Duration? timeout}) → Future<Finder>
Waits for a widget with a key that has testableId as the value.
