horizontal_compass 1.0.2

A customizable horizontal compass (like Skyrim's top bar navigation?), mostly to be used as a horizontal chart that can be looped infinitely.

Horizontal Compass

At first - it's not a regular compass, but because I wasn't able to think of better name... Well, this plugin creates something like horizontal ruler, but idea behind was to use it as a tool for navigation in the app I had to make.

How does it looks like?

Getting Started

It's a simple widget, so no permissions are required. Just type in the terminal:

flutter pub add horizontal_compass

and enjoy the happiness.

Example

Full example you can see in the Example tab, but that's a shorthand:

HorizontalCompass(
  value: 10,
  segments: {
    'segmentA': 30,
    'segmentB': 50,
    'segmentC': 120,
    'segmentD': 160,
  },
  colors: [
    Colors.blueAccent,
    Colors.deepPurpleAccent,
    Colors.orangeAccent,
    Colors.greenAccent,
  ],
);

Widget requires 3 variables to be set:

• value - which represents current value
• segments - a Map<String, double> which tells widget how large are segments, in a Map, String is for a name for segment, double for its length, so in given example it means: segment a should covers value 0 to 30, segment b values 30 to 80, etc.
• colors - is a List<Color> for created segments, so in given example segment a is blue, segment b purple, etc.

Customization

Widget allows you to customize its look and behavior.
