• TouchEvent constructor takes a map argument, strong mode catches these failures in our tests.
• Web_audio AudioScheduledSourceNode.start (inherits in OscillatorNode too) e.g., operation void start([num when]); AudioBufferSourceNode.start([num when, num grainOffset, num grainDuration]) can't be overloaded void start2([num when, num grainOffset, num grainDuration]) Attributes of type double changed to type num table of attributes changed. onWheel event exposed Created for union of two kinds of canvas HTMLCanvasElement and OffscreenCanvas interface WebGLCanvas all other RenderingContext readonly attribute WebGLCanvas canvas; interface WebGLRenderingContext readonly attribute HTMLCanvasElement canvas; KeygenElement was removed in Chrome 57 IDBFactory.webkitGetDatabaseNames() constructor removed in Chrome Depreciated FileError and DomError have been removed use DomException error.code replaced with error.name (e.g., see fileapi_directory_test.dart) Additional because FileError is gone there is no easy way to determine which errors are File only errors.
