Update

• New shorthand Align.center. It has same semantics as of Flutter's Center widget.

• Container widget:

  • Added margin property, that let's you set margin around Container.
  • Added padding property, that let's you set padding space inside Container.

• Custom alignments for positioning a widget on desired locations.

  •   Align(
          alignment: Alignment(80, 40); // top 80% & left 40% 
          ...
    

Core update

• Widget are now smart enough to issue changes to DOM only when required. Previously a widget always issue update to part of its interface that might or might not have affected by state change in parent because this is the easiest way to ensuret that its corresponding DOM is always up-to-date. From now, widgets will issue updates to DOM only if there description has changed.

  For example, in below code, Text widget will never issue a update no matter how many times you do toggle.

  Text(isClicked ? "hey" : "hey")
  

  This feature gets more effective in nested widgets. Take a look at another example,

  Align(
      alignment: isClicked ? Alignment.center : Alignment.center,
      child: Container(
          style: isClicked ? "red" : "red",
          child: Text(isClicked ? "hey" : "hey"),
      ),
  ),
  

  Above Align widget will affect DOM only once when its being built. It'll never issue a DOM update during rest of its lifetime.

Changes:

• sizingUnit is renamed to sizeUnit
• positioninUnit is renamed to positionUnit

Update

• Allow creation of minified and optimized builds.

Core update
