- A refactor that moves the semantics declaration from detectors to recognizers to allow custom recognizers to respond to semantic gectures.
- Renames all handlers related to semantics from Gesture* to Semantics*.
This PR solves two problems: currently, the onExit is called for a mouse pointer the moment the removal message is received, except that by the time it actually calls it, there is no _lastEvent for it in the mouse tracker (it's already been removed), resulting in an event being passed to the onExit that contains nulls for the position. Also, removePointer events don't actually get created with a position, although they easily could be, so that even the the _lastEvent in the mouse tracker were still populated, it would still give a null position and delta.
This PR adds support for the position and delta in a PointerRemovedEvent, and populates them. In addition, when a remove event is received, it doesn't actually remove the pointer until the mouse position check that gets scheduled actually happens.
Updates documentation and non-public API to use American spellings for
consistency with the rest of the codebase.
No changes to behaviour... other than how it's spelt.
This changes Listener to trigger enter/move/exit in all Listeners below the pointer, not just the leaf region (the first region hit). This is because we need to allow listeners to be nested so that, say, a widget that handles changing color on hover, but also is wrapped in a Tooltip (that handles hover) can trigger both actions, not just one.
To that end, I added a findAll to Layer, similar to the existing find method that was previously used. It returns an iterator over annotated layers which match the given data type.
Since the findAll is implemented as returning an Iterable (and is sync*), I re-implemented the find routines as just returning the first result from findAll, since that should be just as efficient, and would then prevent duplication in the implementation.
* Revert "Revert "Remove pressure customization from some pointer events (#30414)" (#30873)"
This reverts commit f34c2ef0a31b7d955035576eeedb0cee7508b2a8.
* Revert pressure removal of PointerUpEvent
* Replace PR with an issue
* Add tests for fromMouseEvent
* Revert "Revert "Add buttons to gestures (#30339)" (#31801)"
This reverts commit 8fd7fa492aaad0d0d4aa062d71b1ecba8b0d4f44.
* Synthesise kPrimaryButton for unknown devices
* Change TestPointer to a better API
* Callbacks of tap, long press, drag, and double tap GR respond to only primary events.
* Add "secondary" callbacks to tap.
* Recognizers only compete on events if there are any related callbacks.
* Add "kSecondaryButton" constant.
* Fix: ui.PointerChange.remove might contain position change, but we used to expand it into a Cancel and Remove, neither of which allows position change. A Hover event is added, and a test is updated accordingly.
* Fixed the issue where a PointerMoveEvent and a PointerCancelEvent do not receive the correct pressure.
* Refactor the calculation of delta into deltaTo.
Adds support for discrete scroll events, such as those sent by a scroll wheel.
Includes the plumbing to convert, dispatch, and handle these events, as well as
Scrollable support for consuming them.
* add trailing commas on list/map/parameters
* add trailing commas on Invocation with nb of arg>1
* add commas for widget containing widgets
* add trailing commas if instantiation contains trailing comma
* revert bad change
* Breaking change which sets the default DragStartBehavior to DragStartBehavior.start and changes WidgetTester.drag and WidgetTester.dragFrom by breaking the moveBy function call into multiple pieces.
This implements support for hovering mouse pointers, so that mice connected to Android devices, and ChromeOS devices running Android apps will work properly.
It teaches flutter_test about hover events, which required changing how they are created and used.
Also modifies AnnotatedRegion to allow a region that can be located someplace other than just the origin.
Along with tests for all of the above.
Fixes#5504
* the onStart callback will report the location of the pointer where it wins the gesture arena by default instead of the pointer down location. Fixes all tests related to changing this default value.
* Adds start behavior option to the drag gesture recognizer and makes it the default option when a drag gesture recognizer is created. Also fixes all the tests to work correctly with the new default behavior.
