      Deprecate VelocityTracker default constructor and added VelocityTracker.withKind constructor (#66043)
      
      We've gotten feedback that the VelocityTracker change was disruptive, though it did not break any of the flutter framework or customer tests. In order to make the change non-breaking, PointerDeviceKind parameter can be made optional.
      
      Nevertheless, this parameter should be provided so that the existing touch handlers can use more accurate gestures on mouse/stylus inputs, so we can encourage this by deprecating the default constructor and pointing users towards the VelocityTracker.withKind constructor that takes a non-optional parameter

      [framework] make hit slop based on device pointer kind for drag/pan/scale gestures (#64267) · 29898812
      Jonah Williams authored
      Currently the framework uses fairly large "hit slop" values to disambiguate taps from drags/pans. This makes sense on touch devices where the interaction is not very precise, on mice however it can feel as if the UI is lagging. This is immediately noticeable on our infra dashboard, where it takes almost half of a grid square of drag before the actual drag kicks in.
      
      One potential solution is to always use smaller constants depending on whether the interaction is mouse or touch based. The only reasonable choice is to use the pointer device kind and not target platform - same platform can have different input sources. This requires exposing the pointer device kind in a few new places in several of the gesture detectors, and using the enum to compute the correct hit slop from an expanded set of constants.
      
      This almost works, however there are a few places (notably ListViews) which uses the touch hit slop as a default value in scroll physics. It does not seem like it will be easy to disambiguate a user provided scroll physics constant from the default and/or adjust it somehow - this might require significant changes to scroll physics which I have left out of this PR.
      
      This PR does not adjust:
      
      kTouchSlop used in scroll_physics.dart's minFlingDistance
      kTouchSlop used in PrimaryPointerGestureRecognizer/LongPressGestureRecognizer

      License update (#45373) · 449f4a66
      Ian Hickson authored
      * Update project.pbxproj files to say Flutter rather than Chromium
      
      Also, the templates now have an empty organization so that we don't cause people to give their apps a Flutter copyright.
      
      * Update the copyright notice checker to require a standard notice on all files
      
      * Update copyrights on Dart files. (This was a mechanical commit.)
      
      * Fix weird license headers on Dart files that deviate from our conventions; relicense Shrine.
      
      Some were already marked "The Flutter Authors", not clear why. Their
      dates have been normalized. Some were missing the blank line after the
      license. Some were randomly different in trivial ways for no apparent
      reason (e.g. missing the trailing period).
      
      * Clean up the copyrights in non-Dart files. (Manual edits.)
      
      Also, make sure templates don't have copyrights.
      
      * Fix some more ORGANIZATIONNAMEs

      Increase the touch slop. (#11419) · 87445e59
      Ian Hickson authored
      It was 8.0. It's now arbitrarily 18.0.
      
      Changing this required adjusting some tests. Adjusting the tests
      required debugging the tests. Debugging the tests required some tools
      to help debugging gesture recognizers and gesture arenas, so I added
      some. It also required updating some toString() methods which resulted
      in some changes to the tree diagnostics logic.
      
      Also I cleaned up some docs while I was at it.

      Changes to the drag gesture detectors and the velocity tracker (#7363) · 11d1d54c
      Ian Hickson authored
      - more dartdocs for the drag typedefs
      
      - more toStrings to aid debugging
      
      - require the position for DragUpdateDetails since we were omitting it
        in some places
      
      - add the primaryVelocity to DragEndDetails so that consumers don't
        have to themselves track the axis in question
      
      - fix the velocity tracker so that it doesn't walk the null data.
        Previously, near time t=0 (which pretty much only matters in tests,
        but it does matter there) we would walk the velocity data and then
        also walk missing data, treating it as Point.zero with t=0.
      
      - simplify some of the velocity tracker; e.g. instead of trying (and
        failing?) to clear the velocity tracker when the pointer stalls,
        just drop the data before a stall during the velocity estimation
        (where we redundantly had another bigger horizon anyway).

      Add a Velocity class to be explicit about units · 4fb47600
      Adam Barth authored
      We were using an Offset, which represented pixels/second, but it wasn't
      clear to clients whether that was pixels/ms. Now we use a Velocity class
      that is explict about the units.
      
      Fixes #1510
      Fixes #785

      Provide a Draggable that starts on drag · 8e279f32
      Hixie authored
      This lets it cooperate with other gestures like tap.
      
      The way I implemented this was to refactor the entire Draggable gesture
      logic to use a new kind of gesture detector called
      MultiDragGestureRecognizer. It works a bit like
      MultiTapGestureRecognizer but for drags.
      
      Also some tweaks to the velocity estimator.

      PointerInput refactor · f1625556
      Ian Hickson authored
      Instead of PointerInputEvent having a "type" field, we now have a
      different class for each pointer type.
      
      This has ripple effects throughout the system.
      
      I also did code cleanup in affected files while I was there.
