Connector constructor Null safety

const Connector(
  1. {Key? key,
  2. Axis? direction,
  3. double? space,
  4. double? thickness,
  5. double? indent,
  6. double? endIndent,
  7. Color? color}
)

Implementation

const Connector({
  Key? key,
  this.direction,
  this.space,
  this.thickness,
  this.indent,
  this.endIndent,
  this.color,
})  : assert(thickness == null || thickness >= 0.0),
      assert(space == null || space >= 0.0),
      assert(indent == null || indent >= 0.0),
      assert(endIndent == null || endIndent >= 0.0),
      super(key: key);
