* Replace PanGestureRecognizer in TextSelection with TapAndDragGestureRecognizer * add tracking of _DragState to new tap_and_drag recognizer and remove some legacy double tap code from text_selection.dart and add logs" * add dragTapCount, a tap count that is persistent for an entire drag and is set to null on drag end vs the regular tap count which is reset on a timer * basic double tap to drag functionality and add a local dragTapCount in text_selection.dart to use with the timer callback * Add offsetFromOrigin and localOffsetFromOrigin to DragUpdateDetails similar to LongPressMoveUpdateDetails, eliminates the need to hold the state of lastDragStartDetails * make a generic baselongpressgesturerecognizer * Revert "make a generic baselongpressgesturerecognizer" This reverts commit aad8f7433bd01e4cd016d527af832c3b1f15fac5. * rename tap_and_drag to selection_recognizers * add mixin for consecutivetap * tap and long press gesture recognizer * Revert "Revert "make a generic baselongpressgesturerecognizer"" This reverts commit 181350c36718f644eada3e45c1b7b5939f90a340. * Revert "Revert "Revert "make a generic baselongpressgesturerecognizer""" This reverts commit 4d69775967858dfd66dd9429e1713da598908a85. * Add support for secondary button clicks on drag gesture recognizer and separate drag end and tap up callback * get test running * rename tapCount to consecutiveTapCount * dispose timer properly * add some comments to tests * Add comments * Make ConsecutiveTapMixin private and move logic to increment tap count into mixin * stop tracking pointer when gesture is rejected and detect drags on touch devices * onCancel for TapAndDrag * have the TapAndDragGestureRecognizer handle tap downs and tap ups on touch and mouse devices * add drag to move cursor for android and iOS, and pointer device kind to DragUpdateDetails * get tests running * refactor TapAndDragGestureRecognizer moving some logic into _check methods * Handle cancel properly on TapAndDragGestureRecognizer, having both onTapCancel and onDragCancel, also fix tests * Fix test mouse drag selects and cannot drag cursor, save _initialPosition based on dragStartBehavior (either on tapDown or dragStart) * determine if drag has a sufficient global distance to accept and fix some cancel behavior, making _checkCancel clearer * give up pointer on drag end * properly stop tracking pointer, fixes test for right click on Apple and non-apple platforms * clean up some comments from last commit * remove drag on touch for now * fix Can select text by dragging with a mouse due to dragStart only being fired on the first PointerMoveEvent, the previous pan gesture recognizer would fire both dragStart and dragUpdate * Revert "fix Can select text by dragging with a mouse due to dragStart only being fired on the first PointerMoveEvent, the previous pan gesture recognizer would fire both dragStart and dragUpdate" This reverts commit 124dc79bc3389672c76d7c014ce04edab297abc6. * correctly use _initialPosition for checkStart and call _checkUpdate after _checkStart if localDelta is not zero * updates * fix double tap chains * Add docs * Address analyzer * more analyzer, only issues left are with print statements * add deadlineTimer to fix conflict with ForcePressGestureRecognizer * Revert "add deadlineTimer to fix conflict with ForcePressGestureRecognizer" This reverts

a double tap + drag was being registered and not a single tap, added a duration to pumpAndSettle to fix this * remove TapAndLongPressGestureRecognizer * fix cupertino text field tests related to shift + tap + drag * deadline timer try 2 * more logs * Should reset taps when tap cancel is called, and should wait until gesture is accepted to initiate a drag * should clear _down and _up when gesture is

is gone * Do not start selection drag on Android, iOS, and Fuchshsia touch devices if renderEditable does not have focus, this fixes many scubas * Address reviewer comments * fix test * TapAndDragGestureRecognizer should wait for other recognizer to lose before winning the arena * Address review comments * Dont check for drag if the start was already found * Only check for a drag if

Flutter is Google's SDK for crafting beautiful, fast user experiences for mobile, web, and desktop from a single codebase. Flutter works with existing code, is used by developers and organizations around the world, and is free and open source.
Documentation
For announcements about new releases, follow the flutter-announce@googlegroups.com mailing list. Our documentation also tracks breaking changes across releases.
Terms of service
The Flutter tool may occasionally download resources from Google servers. By downloading or using the Flutter SDK, you agree to the Google Terms of Service: https://policies.google.com/terms
For example, when installed from GitHub (as opposed to from a prepackaged
archive), the Flutter tool will download the Dart SDK from Google servers
immediately when first run, as it is used to execute the flutter
tool itself.
This will also occur when Flutter is upgraded (e.g. by running the flutter upgrade
command).
About Flutter
We think Flutter will help you create beautiful, fast apps, with a productive, extensible and open development model, whether you're targeting iOS or Android, web, Windows, macOS, Linux or embedding it as the UI toolkit for a platform of your choice.
Beautiful user experiences
We want to enable designers to deliver their full creative vision without being forced to water it down due to limitations of the underlying framework. Flutter's layered architecture gives you control over every pixel on the screen and its powerful compositing capabilities let you overlay and animate graphics, video, text, and controls without limitation. Flutter includes a full set of widgets that deliver pixel-perfect experiences whether you're building for iOS (Cupertino) or other platforms (Material), along with support for customizing or creating entirely new visual components.
Fast results
Flutter is fast. It's powered by the same hardware-accelerated 2D graphics library that underpins Chrome and Android: Skia. We architected Flutter to support glitch-free, jank-free graphics at the native speed of your device. Flutter code is powered by the world-class Dart platform, which enables compilation to 32-bit and 64-bit ARM machine code for iOS and Android, as well as JavaScript for the web and Intel x64 for desktop devices.
Productive development
Flutter offers stateful hot reload, allowing you to make changes to your code and see the results instantly without restarting your app or losing its state.
Extensible and open model
Flutter works with any development tool (or none at all), and also includes editor plug-ins for both Visual Studio Code and IntelliJ / Android Studio. Flutter provides tens of thousands of packages to speed your development, regardless of your target platform. And accessing other native code is easy, with support for both FFI (on Android, on iOS, on macOS, and on Windows) as well as platform-specific APIs.
Flutter is a fully open-source project, and we welcome contributions. Information on how to get started can be found in our contributor guide.
