rainbow_gradient 0.0.1

rainbow_gradient #

Build Status codecov

An easy way to add Rainbows to your Flutter apps! Provides a RainbowGradient which implements the abstract Gradient class, and can be used anywhere you'd use a normal LinearGradient or RadialGradient, such as the gradient property of a BoxDecoration.

Usage #

Container(
  height: 250.0,
  decoration: BoxDecoration(
    gradient: RainbowGradient(
      begin: Alignment.topLeft,
      end: Alignment.bottomRight,
      colors: <Color>[
        const Color(0xFFFF0064),
        const Color(0xFFFF7600),
        const Color(0xFFFFD500),
        const Color(0xFF8CFE00),
        const Color(0xFF00E86C),
        const Color(0xFF00F4F2),
        const Color(0xFF00CCFF),
        const Color(0xFF70A2FF),
        const Color(0xFFA96CFF),
      ],
    ),
  ),
);

3 out of 3 API elements have no dartdoc comment.Providing good documentation for libraries, classes, functions, and other API elements improves code readability and helps developers find and use your API.

Maintenance suggestions

The package description is too short. (-11 points)

Add more detail to the description field of pubspec.yaml. Use 60 to 180 characters to describe the package, what it does, and its target use case.

Package is pre-v0.1 release. (-10 points)

While nothing is inherently wrong with versions of 0.0.*, it might mean that the author is still experimenting with the general direction of the API.
