BorderSide constructor Null safety

const BorderSide(
  1. {Color color = const Color(0xFF000000),
  2. double width = 1.0,
  3. BorderStyle style = BorderStyle.solid,
  4. StrokeAlign strokeAlign = StrokeAlign.inside}
)

Creates the side of a border.

By default, the border is 1.0 logical pixels wide and solid black.

Implementation

const BorderSide({
  this.color = const Color(0xFF000000),
  this.width = 1.0,
  this.style = BorderStyle.solid,
  this.strokeAlign = StrokeAlign.inside,
}) : assert(color != null),
     assert(width != null),
     assert(width >= 0.0),
     assert(style != null);
