fcharts

Build Status Pub Status

A work-in-progress chart library for Flutter. Until version 1.0.0 the API is subject to change drastically. Needless to say, fcharts is not production ready.

The goal of this project is to allow for creating beautiful, responsive charts using a simple and intuitive API.

Inspired by Mikkel Ravn's tutorial on Flutter widgets and animations. If you have used Recharts (ReactJS library) you will find the high level API to be somewhat familiar.

Example Usage

class SimpleLineChart extends StatelessWidget {
  // X value -> Y value
  static const myData = [
    ["A", "✔"],
    ["B", "❓"],
    ["C", "✖"],
    ["D", "❓"],
    ["E", "✖"],
    ["F", "✖"],
    ["G", "✔"],
  ];
  
  @override
  Widget build(BuildContext context) {
    return new LineChart(
      lines: [
        new Line<List<String>, String, String>(
          data: myData,
          xFn: (datum) => datum[0],
          yFn: (datum) => datum[1],
        ),
      ],
      chartPadding: new EdgeInsets.fromLTRB(30.0, 10.0, 10.0, 30.0),
    );
  }
}

The above code creates:
