d_chart

D'Chart is a package for compact chart widgets. This package is a remake of the charts_flutter package. The remake chart types include bar, line, pie, donut and gauge. The use of this package is made as concise as possible, but with the best chart display.

    ],
    fillColor: (pieData, index) {
        switch (pieData['domain']) {
