A new Dart Editor build is available at  www.dartlang.org/editor .  This build introduces a couple of quick assist items. The first assist item lets you combine an 'if' statement with an inner 'if' statement. Place the cursor over the starting if, press cmd-1, and hit return. That converts the following code:    if (!(object is Person)) {     if (object.name.beginsWith( 'R' )) {       nextItem = object.name;     }   } to this: if (!(object is Person) && object.name.beginsWith( 'R' )) {   nextItem = object.name; } The other quick action converts  (!(item  is A )) to (item is! A)  format: Place cursor over is, press cmd-1, and hit Return to convert to to is! format Eric Clayberg  fills us in on the changes  introduced in this build: Opening type from omni box opens corresponding file. F3 works for URL in impor...
