contour_gradient 1.1.0

A ShapeBorder and InputBorder that paint a gradient along the length of any OutlinedBorder shape, for containers, buttons, cards, chips and text fields.

1.1.0

• Added withGradient, an extension on OutlinedBorder that paints any shape with a gradient along its border, keeping the shape's own side: const StadiumBorder(side: BorderSide(width: 2)).withGradient(colors). The README and the example now use it. The ContourGradientBorder constructor is unchanged, and is still the way to make a const border.

1.0.3

• Added a showcase GIF to the package page on pub.dev.

1.0.2

• Behavior change: on closed borders the gradient no longer blends from the last color back into the first. It runs from the first color to the last, with a hard edge where its end meets its start. To keep the previous look, repeat the first color at the end of colors: with evenly spaced colors, [a, b, c, a] looks the same as [a, b, c] did before. With stops, the border is now the first color before the first stop and the last color after the last stop.

1.0.1

• Fixed a BeveledRectangleBorder shape's border being twice as wide as its side, as Flutter's own BeveledRectangleBorder paints it. It is now as wide as its side everywhere, on the bevels too.

1.0.0

Initial release.

• ContourGradientBorder: an OutlinedBorder that paints a gradient along the length of any OutlinedBorder shape. Supports stops, hard stops, and startOffset for moving the gradient along the border. On closed borders the gradient wraps around and evenly spaced colors each get the same share of the border.
• A LinearBorder shape runs the gradient along only the edges it draws, so an underline shows the whole gradient from left to right. Unlike Flutter's own LinearBorder, its edges are painted in the right place when the box does not start at the origin, as in a Container, and without a faint line where two edges meet.
• ContourGradientInputBorder: the same for InputDecoration, with a gap for floating labels like OutlineInputBorder.
• Both borders interpolate, so they work with implicit animations, and animate to and from plain OutlinedBorders and OutlineInputBorders.
