v1.4.1

• Fix #30: Cannot initialize Dropzone with List.
• Follow more code style conventions.
• Update dependencies.

v1.4.0

• Add an option minDragStartDistance on Draggable to define the minimum distance in
  pixels that is needed for a drag to start (#26). Default is 4 pixels. This allows for clicks with tiny movement. The option clickSuppression has been marked as DEPRECATED as it had the same goal but a misleading name.

v1.3.0

• Align dart version to support Dart 2 (#25).

v1.2.0

• Support for creating a Draggable with List<Element> (in addition to ElementList and Element).

v1.1.0

• Remove cursor files. Support for grab, -webkit-grab, grabbing, and -webkit-grabbing is good enough.

v1.0.0

• Migrate to Dart 2.
• Since Chrome 56 touch event listeners are treated as passive by default. This disables the possibility to call preventDefault on an element which we must do to tell the browser not to scroll while dragging. To fix this in Chrome we set the touch-action css property. With this Chrome will not scroll (none) or only scroll in one direction (pan-y or pan-x).
