pixel_border

A package to render shapes or borders of widgets with pixelated corners.

Usage

PixelBorder can be used the same way built-in ShapeBorders are, by setting the shape property on any Widget supporting it.

Some examples include:

Drawing an orange square border where all corners are rounded and drawn with "pixels" of size 2.0

Container(
  decoration: ShapeDecoration(
    shape: PixelBorder.solid(
      borderRadius: BorderRadius.circular(4.0),
      pixelSize: 2.0,
      color: Colors.orange,
    ),
  ),
  height: 42.0,
  width: 42.0,
);

Setting the default ElevatedButton shape in MaterialApp:

MaterialApp(
  theme: ThemeData(
    elevatedButtonTheme: ElevatedButtonThemeData(
      style: ElevatedButton.styleFrom(
        shape: PixelBorder.shape(
          borderRadius: BorderRadius.circular(10),
          pixelSize: 5,
        ),
      ),
    ),
  ),
);

For corners to be drawn properly, PixelBorder requires the radii defined in borderRadius to be a multiple of pixelSize.
