You can simply create a
Scatter by providing a delegate and a list of widgets.
The delegate is responsible for computing positions.
For example if you want to position your widgets on a circle, you will use the
return Center( child: Scatter( delegate: EllipseScatterDelegate( a: 185.0, b: 185.0, step: 1.0 / count, ), children: widgets, ), );
It may be useful to choose how children are aligned with the computed positions. By default, the center of the widgets will be placed on the positions generated by the delegate.
If you want to be left aligned, you will change the
alignment argument of the
Scatter to be
By default, the Scatter will not try to fill gaps (for performance reasons). You can override this behavior by setting the
fillGaps argument to
For example this is what the above word cloud would look if the
fillGaps argument would be set to
Scatter has built-in delegates which can be highly parameterized:
